I saw this yesterday on Comedy Central and laughed so hard it made my neighbors come over to see what all the noise was about.
This is Jeff Dunham who is a comedian ventriloquist with several puppets in his hilarious arsenal. My favorite is his Peanut act which you'll see below by following the YouTube links. I guarantee you'll laugh... or there is something just plain wrong with you.
