You see them everywhere...They make no sense at all....That's right!! Crack Couples!! What's the crackyest crack couple you've ever seen? It doesn't even have to be anime related!! Mine is:

1. Ulquiorra x Hinata (seriously what's up with that!?) (Bleach x Naruto)

It's kind of hard to make an example of the 'crackiest' couple, since all you'd have to do is throw in two completely random characters and it'd be crack. Also, sometimes couples that don't make sense to some make complete sense to others. Like I know some people who completely love the pairing of Hidan x Shikamaru, but for me that's a complete 'Wtf' because in no way would they ever end up together IMO, but apparently to the fans it's perfectly awesome and happenable.

Crack pairings that personally make no sense to me:
Niibi (Two Tails) x Hidan (both from Naruto)
Kakuzu x Tsunade (both from Naruto, might be possible if the right things happened like something that had to do with money, but it still brought a big 'wtf' moment to me)
Sephiroth x Harry Potter (Final Fantasy VII x Harry Potter)
Legolas Greenleaf x Harry Potter (Lord of the Ring x Harry Potter)
etc. etc.

Wah...Hidan and Tsunade...xD

Really messed up crack pairing:

NarutoxRukia...
(Naruto and Bleach)
Yes, really. xD

I gotta say..I've seen some odd pairings and the one that always weirded me out the most was Melan Blue x Marin from Brigadoon. Seriously, wtf is up that??? He's like an organic gundam. xDD

I heard someone or some people had written fanfiction for the Uchiha brothers as a couple....Sasuke and Itachi, which to me is wrong on so many levels....its incest, they don't even like each other and well...homosexual, but I suppose the homosexuality thing is just a minor irk for me, it's the other two factors that make it WTF？

I don't think Hinata x Sasuke was a very good couple...I mean, they RARELY talk.

Speaking about crack pairings...

Xena (Warrior Princess) x Krato's (God of war) Should totally be together *nods*
