Discovered check
I've had some pretty funny ones. In particular, a game where my opponent thought he'd just gotten a pawn with his queen because my bishop was blocking my rook (or queen? I forgot) from defending it. Then the bishop moved out of the way and checked the king...while the rook/queen that was behind the bishop pinned it to the king. Watching him capture the pawn so confidently, then pause for a few seconds and resign, was one of the biggest highlights in my chess journey.
