Who would YOU like to see collaborate?

The question came up in Atlanta, and I think it's an interesting one. With all the twins/triplets/division by chickens in the past few seasons, we've seen some interesting combinations arise--two great teams, an established team helping rookies, a team helping to bring another back from near-oblivion, and so on.

But if you ruled the world, and could have any two (or three) teams collaborate, who would they be? Why? (The latter part is required, although it doesn't have to be a serious reason. )
