The very first wrestling match you saw?
I was thinking about this and damn, this is actually pretty hard.
I'm pretty sure it was a Triple H vs. Shawn Michaels match on Raw in summer 2004? I'm at least positive one of the guys involved was one of them, at least. And not to long after that episode HHH and HBK were meant to shake hands at the end of a Raw episode, but Kane then came and assaulted Michaels.
Either that or a JBL match on SmackDown that aired on Velocity and then had Eddie come out afterwards and JBL saying "no, I'm not gonna fight you again" or something like that. No idea who JBL faced, though. Can't remember.
What about you?
