I want one of these, but I'd like it modified so that whenever ANYONE knocks on the door, it plays a recording of me shouting "FUCK OFF, CUNT!"

Man... I wouldn't use this on my front door, kinda risky. But it's a really great idea for something fun for a kid's bedroom or something! :D

you could easily mod it to sense a light combination through the peephole instead of doing a knock
