There's a few examples I have in mind:

Tatsumaki and Edward Elric (after you answered this question with that, their reactions have been somewhat in my mind and I couldn't stop laughing to myself sometimes)

Naruto and Sasuke (just to see their reactions)

Kirby and somebody else (mostly because I'm curious to see if he can say anything other than "Poyio!" in somebody else's body)

Roshi and probably Erza (not because I'm perverted, but because I want to see Roshi's reaction to Erza's body and Erza's reaction to having her body swapped again)

Tatsumaki and Yoshi (want to see their reactions. Are you noticing a pattern here?)
