That's from south park....This conversation actually took place between a father and a son.
Stan: Hold on guys my dad is calling me for something.
Dad: You've been on you computer all weekend. Shouldn't you go out and socialize with your friends.
Stan: I am socializing R-tard. I'm logged on to an MMORPG with people all over the world and getting XP with my party using team speak.
Dad: I'm not an R-tard.
(dad walks off)
