Jon Stewart not a fan of the north-south position

Admit it, if you're a guy there's something creepy about the north-south position in mixed martial arts. We're guessing it wasn't the intent of B.J. Penn to cover Brian Kilmeade's face with his groin, but it happened. We love it, The Daily Show's Jon Stewart does not (1:12 mark).

Penn appeared on Fox News as part of his big national media tour to push his new book, "Why I Fight" written by David Weintraub.

Below is a photo of Penn's appearance on SiriusXM's Opie and Anthony Show. Penn slaps an armbar on Jim Norton, who happens to be also happens to be big a fan of the sport.

Norton, like many other fans on Saturday, was pretty vocal @jimnorton about Anderson Silva's less than stellar performance.
