Two words: Gomer Pyle.
As for Kristopherson, I don't think he's a bad actor, but he's had some classically stinko roles.
I remember Tom Waits in "Ironweed." I didn't like the movie at all, (it was about as entertaining and uplifting as watching flies land on road-kill) but he was pretty good. I mostly remember that film because it featured Lena Spencer (of Cafe Lena) in a cameo.
