Zilla has this on his site... very funny. If you have'nt seen the the SNL one, watch that one first and then watch the bonus rap battle one. Awesome stuff.

Seriously, click here... is this for real?? I would hide if this was my name.

And check these guys out. I've spent hours looking through all the stuff that they have done.

Improv Everywhere.

From their FAQ:

In August of 2001, I went out to a West Village bar with my college buddies Brandon Arnold and Jon Karpinos. On a whim we decided to pull a prank where I would pose as musician Ben Folds. Three hours later, "Ben Folds" was drinking on the house surrounded by women and his "two big fans" were thrown out of the bar for "stealing Ben Folds' wallet". I had always been a prankster, but this experience enlightened me as to how far a prank could be taken. As an actor new to the city, I discovered I could create my own theatre rather than waiting around for someone to give me stage time. I got tired of telling the story to friends, so I typed it up and put it on the web. Improv Everywhere was born.

Ahhhh....good stuff. Have fun!
