Who played the game "penis" on the school bus? Someone whispers penis, then someone louder, and louder... until people are screaming PENIS. Good times... In 6th grade the bus driver actually took us all back to the school for that because (s)he had recently had a sex change and found it offensive
Funny thing is, to this day, we aren't sure if it was a male-to-female, or female-to-male...
