One day in a second grade classroom a teacher says, "O.K. class, today
 were gonna study animal sounds. Can I have the first volunteer?" she says.
 This kid stands up and the teacher says "O.K., What kind of sound does a
 cow make?" The kid says "Moo-Moo". Very good said the teacher. Now whose
 the next volunteer? This other kid gets up and the teacher asks "What kind
 of sound does a horse make?" So the kid says "Hurr-rr-rr". Very good the
 teacher says now next volunteer? This black kid gets up and the teacher
 asks O.K. what kind of sound does a pig make? The kid says "HANDS BEHIND
 YOUR HEAD MOTHERFUCKER"!!!
