Jeff Dunham is hilarious. He was the first thing that came to mind when I saw the title to this post. You should watch his other videos, they're great.
That's because unlike other ventriloquists, he doesn't focus on impressing people with his talent. He treats his show like a 2 man act, as though the dummy was an actual person. Unlike actual people though, his dummies have personalities you generally would never find humorous in person. I love watching him!
I think my house is haunted.
Whys that?
My Wife is there... everytime I walk in, I hear a voice saying "Get out!"
