If there's one thing we know about Jason Dufner, it's that he doesn't mind being the butt of a joke.

We also know that he doesn't mind (prefers, probably) grabbing his wife's butt after winning the PGA Championship.

While the jokes have mostly (good-naturedly, of course) been on Duf, turns out he's got jokes of his own.

On Tuesday night, Dufner hosted the PGA champions dinner at Churchhill Downs. The 2013 champ served up some southern staples such as shirmp and grits, and chicken biscuits. But the main event, er, course, was the "butt rubbed" filet mignon.

And just when I thought we'd all moved on from the butt grab jokes ... there goes Duf, bringing up the rear.
