Once when I was younger, let's say age 6 or 7....I was getting off the school bus, and one of the boys who I went to school with (Chris Spicer) asked me to play a game with him.
He then jumped on me and said "I'm going to hump you".
I was not sure what this meant and said "okay, but then what do I do?"
He said "just lay there, act like you are sleeping".

My mom came up and grabbed him by the neck...game over.

The boy was just as clueless as I was, so this is not some terrible story of lost innocence.
It's interesting to me because I just remembered this twenty years later, and I think it's funny that he thought I should just lay there...HOW BORING.
