Crack Pairings

We all know that the heart of all manga is the relationshis between characters. Bad guys and good guys, friends and foes, etc. But what about romantic relationships? Sure, there's the actual legit pairings, but how much fun are those, really? No, I'm talking about the crack pairings, the people that you know wouldn't touch each other with a ten-foot pole, but you support their 'love' anyway. You know what I'm talking about. Rule 34.

Here's an example: Tsunade and Kimimaro. They don't even have to have met! So post your favorite crack pairings so we can all have a good laugh or wash our heads out with mindsoap for thinking that.
