  • So just to recap 6+6=12, right?

  • @j98765432123 He is NOT retarded. respect people, man. this vid just helped me

  • @j98765432123 1. id rather cut my own arm off than suck your testicles 2. im not a homosexual and thats the worse insult known to man.

  • @h0rsemad suck my left testicle you raging homosexual

  • @j98765432123 to be honest thats not very funny because he's put this on here to help people, and even if he is "retarted" it doesn't matter? he's still a person and you wouldn't want people to laugh at you about something like that, and if you were watching this you probably needed to learn about it, meaning that he knew something you didn't so if anything it should be him laughing at you, your pathetic, grow up and get a life :)

  • this vid helped. i have an exam in 2 hours for grade 12. wish me luck =P

  • hahahahahahah are you retarded
