I thought he was pretty funny the first time I watched him, but most of his puppets aren't that funny at all. The old man one can still garner a chuckle, though.
I like him in some cases. Some characters are funny, some aren't. But his first two shows were pretty funny as a whole. Recently however, I found out that the guy now has a show on Comedy Central and after watching half an episode all I saw was LAME.
The Jeff Dunham Show. If the title isn't scary enough, go check it out on Youtube and be repulsed!
You mean by the way that little effort is put into them in any attempt to make a coherent story? That's what I've noticed. The old YTPs are the best. I just like the cock jokes.
