Shirtless Kieffer Delp vs. The Situation: Whose Six Pack Is Supreme?

Time to put down your work, take your iPhone into a discreet corner, and vote on the most important debate in reality TV history. Yep, it's an MTV ab-off, and it's completely glorious.

Meet the contenders: Teen Mom's Kieffer "Wandering Minstrel" Delp and Jersey Shore's The Situation.

Both these brosefs have six packs (eh, four packs) that won't quit, but which washboard would you rather scrub your monokini on? The Situation's stomach looks like a friendly happy face (seriously, it has eyes), and obviously the man necklace just adds to the beauty. But then there's Kieffer, whose taut tummy is itching to be ogled.

Sigh, this is a toughie. We suggest you examine these hot pics for about twenty minutes and then vote on your fave!
