Boing Boing linked to a video of five famous voice-over artists having fun with the clichès in their profession. It's a good time, but my favorite send-up, and favorite trailer in general, is for the documentary on Jerry Seinfeld, The Comedian. Totally original and completely hilarious.

"When your life is no longer your own..."
"What does that mean?"
"...when everything you know is wrong..."
"That's wrong."
"In an outpost..."
"On the edge of space..."
There is no space."

It goes on. You should definitely watch. Now.
