Jeff Dunham

In case you're not familiar with the name, he's a ventriloquist.
Jeff Dunham has a very funny piece about a show he played in front of an audience (hah !) of deaf people (watch on youtube), which is why I was very surprised to see that you can soon see one of his shows on comedy central in germany.... yes, in german. They actually went so far as to dub a ventriloquist. In case you want to check it out, there's a small segment of the same thing here (my apologies if youtube won't let you watch it like it won't let me watch many things that can be seen on youtube in america).
