grand theft auto san andreas 

The Game that these two guys planned on getting before it came out that I am playing right now. The game that along with 8 mile got every white kid in this town saying "wadup doe". It's packed with all kinds of awesome mini games and possibilities for advancement to different levels of leadership and ownership. Straight gangsta.

After playing Grand Theft Auto San Andreas, life just doesn't seem all that dangerous.

It starts out when a man is fucking a girl from behind, while she is facing out a window. Another man sneaks out from a nearby hiding place. Man 1 quickly pulls out while Man 2 quickly jumps in. Man 1 sneaks out, runs outside, and waves up to the unsuspecting girl at the window.

Spencer and I totally nailed that grand houdini!
