 Item number SCP-645 Object Class Euclid Special Containment Procedures SCP-645 is to be kept in a padded crate, 2 meters by 2 meters by 1 meter. Personnel within a 10 meter radius of SCP-645 are to refrain from all statements which may be considered untruthful or deceitful. SCP-645 is to be cleaned after each activation. Description SCP-645 is a large disc of Pavanazetto marble with a humanoid face carved into it, similar to the famous Baca de la Verida carving in the Church of Santa Maria in Cosmodin in Rome, Italy. As with the Baca carving, the mouth and eyes are empty holes. Unlike with the Baca carving, however, subjects who place their hands inside SCP-645's mouth describe it as warm and moist. SCP-645 embodies and has been hypothesized by Foundation folklorists to be the origin of the lie detection properties attributed to the Baca carving since medieval times. Any subject who tells a lie, see incident report SCP-645-N41 while their hand is within the carving's mouth will activate the carving, which will then bite off the subject's hand at the wrist and swallow it. High-speed cameras have revealed that this process, which lasts less than 0.3 seconds, involves the manifestation of lips, gingiva, and disproportionately large incisor teeth. The lips cauterize the injury via an unknown mechanism after which the lips, gingiva, and teeth de-manifest. The force exercised by the teeth has not been accurately measured but is sufficient to sever a steel rod held in the hand being bitten off. Probes of SCP-645's mouth in its inert state have revealed no esophagus. As such, the ultimate fate of the severed hands is unknown. RFID tags implanted in the hands of D-class personnel have been unlocatable, and sonograms of SCP-645 indicate that it is solid Pavanazetto marble with no inclusions. Recovery. SCP-645 was discovered during routine archaeological excavations in F*** Italy in 19 F***. The slab of marble bearing the carving was not attached to any building and had been bricked over. Archaeologists f*** expressed the opinion that it seemed to have been deliberately buried. 48 hours after being discovered, SCP-645 mutilated a graduate student who had been participating in the excavation. Foundation agents in the Italian Ministry of Cultural Heritage and Activities intercepted the injury reports and retrieved the object. Incident Report 645N41 On W***, D-45-95-1 was enlisted for experiments to study both the criteria by which SCP-645 assesses statements as lies and the mechanism by which it severs hands. Unexpectedly, D-45-95-1 was able to deduce SCP-645's anomalous properties prior to testing due to cultural knowledge of the properties folklorically attributed to the bokeh carving. Consequently, D-45-95-1 disobeyed instructions as to how we should interact with SCP-645, which ultimately revealed further anomalous properties. Transcript of Audio Log Dr. Rensberg, insert your left hand into the carving's mouth. Good. Now, say the phrase, the sky is bright green. D-45-95-1 Silence. Dr. Rensberg. D-45-95-1 D-45-95-1 Ugh, the sky is green is what these guys told me to say. Dr. Long. What was that? Dr. Rensberg. Why didn't it activate? Dr. Long. Let's try another one. D-45-95-1 Say this. I have six fingers. D-45-95-1 These guys want me to say I have six fingers, but really I don't. Dr. Rensberg. I definitely heard him that time. What do you think you're doing? Dr. Long. You're interfering with the experiment. D-45-95-1 There was a movie. Dr. Rensberg. What? D-45-95-1 In the movie, there was a statue thing that looked like this one, and they said if you put your hand in and lie, it bites your hand off. Note. Said movies subsequently identified as Roman Holiday, 1953, Paramount Pictures, starring Audrey Hepburn and Gregory Peck. Dr. Rensberg. That's ridiculous. Are you going to comply with instructions or do we have to get the guard involved? Dr. Long. No, wait. Let's hear him out. Surely intent matters. Guard. Do you want me to... Dr. Rensberg. Hmm. You know, that's actually a very good... At this point, D-45-95-1 removes his hand from SCP-645's mouth. Dr. Long. Hey, keep your hand in. Dr. Rensberg. Guard, hold his arm. Keep his hand in its mouth. D-45-95-1's hand is forcibly reinserted into SCP-645's mouth. Dr. Long. Let's see, where were we? Oh, yes. What was this movie about? D-45-95-1. Plot synopsis omitted. Dr. Long. Hmm. Well, we'll have someone look that up. Thank you for the information. But honestly, you know the difference between movies and real life, don't you? Do you really think the carving will bite your hand off just because some guy in a movie told a story about it? You even said that the guy in the movie was lying about it, right? D-45-95-1. I don't know. Look, I wouldn't have believed... I mean, I don't think I would have believed it. Before I came here and saw all the weird shit you guys have got here, all the monsters and shit, but now that I've seen it all, it made me think maybe it... I mean, that's how I'm explaining it right now. It didn't all go through my head word for word right then, but you know, people... I mean, a lot of people, maybe not everybody in the world, I don't know. A lot of people are like that. What's the question? I lost a kind of lost track. Only kind of. I mean, we're still talking about the statue, right? Dr. Rensberg. Yes. Do you think, just because of the movie, that the statue will... D-45-95-1. Oh, right, right, yeah, I... Well, I don't know for sure, but I'm thinking that maybe it will because of... Well, because of a bunch of stuff. Like, part of it is that movie that I saw a part of on TV one time, at least one time. And I thought it was just a load of crap. I mean, looking back at what I was thinking back then, I guess I didn't really believe it because it was just something in a... I thought it was just something in a movie. And stuff in movies isn't... I mean, a lot of stuff in movies isn't really real, not like real life. At least that's not what I always thought, except not always like all the time. Oh God, please don't bite my hand off. Dr. Long. Interesting. Let's see what we had on the list. Ah, yes. D-45-95-1. What's your name? D-45-95-1. That's kinda compli... I mean, the question isn't. I guess the answer isn't complicated, but the answer is. It's kinda complicated. Like, the name that everybody called me. Well, not everybody, everybody. Like, not everybody in the world, but you know, people in my life? Most of the... A lot of the people in my life. They called me... But when I was born, my name was... I mean, like, a little while after I was born, my parents said my name was... So that COULD be my name too, sort of. And... You guys call me D-45-95-1. Or that's what you've been calling me. Maybe you'll change your minds later. I dunno, it's up to you, I guess. Dr. Rensberg. Fascinating. How about... D-45-95-1. Say... 2,809 is a prime number. D-45-95-1. Are you f***ing serious? I... Dr. Rensberg. Guard? D-45-95-1. No, no! Look, I dunno what that means. I mean, I know those words by themselves. But the whole thing doesn't... I mean, obviously, it's some sort of... Well, obvious maybe isn't the right word. But I guess it's some kind of math thing? Like, I remember hearing about prime numbers on the... I kinda remember hearing about them. And I kinda think it was on the news. But I'm not like a hundred percent sure. Oh jeez. And I was never... Well, I mean, when I was in school I wasn't... I didn't do that good in math when I was in school. A lot of the time. Except when I cheated. Except maybe that's not the same as me doing good in math. And I guess I did okay. Back when I was real little and it was super simple. Dr. Long. Impressive. How about... Dr. Rensberg. Yes, that's a good one. D45951. Do you ever lie? D45951. I mean... I... Everybody... I told... I used to tell... In the past. I said stuff that maybe wasn't... Okay, no, no maybe. Stuff that wasn't true. But I'm not gonna... I mean, I don't think I'm gonna... I mean, right now... With my hands stuck in this thing's mouth... I'm trying real, real hard... To not say anything that's not super absolute true. Dr. Long. Wow. You're really, really scared, aren't you? D45951. Oh, f*** yes. Dr. Rensberg. Just because of the movie? D45951. Look, we went... I mean, I went over that already. It's because of the movie that I know. That I think I know what it is. And seeing all the... Seeing the monsters you got here. I don't know if I saw all of them. Seeing the monsters is what tells me that it's for... That maybe. It's for real. Plus, I mean... Why would you be doing this stuff with me sticking my hand in here and then you telling me to say s*** if you weren't expecting it to bite my hand off? Right? Why else would you have this a**hole... This guy... Holding my arm so I can't... So I probably... Can't pull my hand out. Dr. Long. He has a point. Dr. Rensberg. Oh, don't go feeling sorry for him. D45951. Do you deserve this? D45951. Uh, what? Dr. Rensberg. This! The way we're treating you being D-class personnel. Do you deserve it? D45951. You don't have to yell at me. Dr. Rensberg. Did you commit the crimes you were convicted of committing? Yes or no? D45951. I... look. The f***ing cop was self-defense, okay? Her me, right? Dr. Rensberg. And the others? Were they all self-defense too? Guard. Uh, sir. D45951. Well, I mean... Look, they were witnesses and... I mean, they coulda... I mean, I thought they coulda... I... look, it was... I mean, no. You know what? No. No, they f***ing weren't self-defense. I didn't think I had to kill them. I didn't think I had no f***ing choice. I killed them because I wanted to. Because I wanted them to be dead. Because I like killing. Because I like the way it makes me feel. Because it means I have power. That honest enough for you, you big stone f***. At this point, SCP-645 forcibly ejected D45951's hand from its mouth. High-speed cameras show that its lips manifested and then contorted, apparently spitting the hand out. The lips had completely de-manifested within 0.2 seconds. D45951. What the f***? Dr. Long. Did you take your hand out? Put your hand back in! Guard, put his hand back in! D45951. Oh, I... Guard, I can't. It won't go in. It's not accepting his hand, sir. It's blocking him. Dr. Rensberg. What? Subsequent examination revealed that although Dr. Rensberg, Dr. Long, and Guard Dickinson were each able to insert a hand into SCP-645's mouth, D45951 was not. Experiment was aborted. Dr. Rensberg. Out of here, we'll have to requisition another D-class. Dr. Long. Preferably one who doesn't watch romantic comedies? D45951 is escorted out of the testing chamber. Dr. Rensberg. Well, at least we got some results. I wonder what specifically triggered it to reject his hand. Dr. Long. Maybe he really was honest enough for it. Creepy little f***er. Hey, that reminds me. How did you know the details about what he did? Dr. Rensberg. Seriously, man? I was bluffing. At this point, SCP-645 opened its mouth to a width of approximately 70 centimeters and propulsed an elongated frog-like tongue four meters across the room at Drs. Rensberg and Long. The tongue coiled around Dr. Rensberg's right wrist and severed his hand then retracted colliding with Dr. Long and breaking his left shoulder in the process. The tongue had fully returned to the mouth and the mouth had returned to its normal size within 0.7 seconds. Both doctors survived as a result of prompt medical attention. However, Dr. Rensberg's hand was too badly damaged to be reattached. Note. After a thorough review of not only incident 645N41 but of all footage of personnel and proximity to SCP-645, I have come to the conclusion that SCP-645 is most likely sapient. This was not the first time that personnel and proximity to SCP-645 have lied or otherwise been less than honest. However, in light of D45951's admittedly impressive performance in avoiding any untruths and of 645's unprecedented rejection I feel that 645's attack on Dr. Rensberg immediately after he admitted to having deceived D45951 was a conscious act motivated by resentment and antipathy. Incident 645N41 also revealed that the scope of 645's anomalous properties is far greater than we had suspected. In particular, it can no longer be considered to pass the locked box test. I therefore request that its object class be upgraded to Euclid. Site director R.
