Bristol Palin and "The Situation" were on the same season of 'Dancing With the Stars,' but it's hard to imagine the pair together in any other context. She's the daughter of the most famous conservative politician in America, and he's ... the guy with the abs from 'Jersey Shore.' But now, Palin and Mike "The Situation" Sorrentino have teamed up for a video that promotes the value of abstinence and safe sex.

It might be noted that there are two issues here:

1) Bristol is now a spokesperson for abstinence, but is best-known for having an out-of-wedlock child as a teenager. Before becoming an abstinence spokeswoman, she told Fox News that abstinence is "not realistic at all."

2) "The Situation" appears on a realty show that revolves around his attempts to have sex with random girls in hot tubs.

On 'The Daily Show' (weeknights, 11PM ET on Comedy Central), Jon Stewart checks out their new PSA -- and his horrified reaction pretty much says it all. He watches the ad, then his eyes bug out, as he tries to avoid mock-vomiting in horror. Maybe it's the use of the nicknames "B. Palin" and "the Sitch" that freaked him out. Or maybe it's the oddness of the Palin/Sorrentino combination.

Candie's -- the foundation behind the ad -- supports safe sex as well as abstinence, which is why "the Sitch" brandishes a pack of condoms repeatedly during the PSA. Here's the full ad, in case you want to check it out for yourself. But watch out -- the full PSA contains approximately 10,246 uses of the phrase "The Situation," and may cause your brain to explode.
