What's the coolest thing you've ever done in a videogame?

Just curious. Define "cool" any way you like. Whether it was due to your skills, or you're applauding the developers for the experience they gave you, I'm just trying to get a sense of things that can't be measured by a normal review.

Probably doing some really cool move in Melee and KOing the other guy when he thought he was going to beat me. Hard to think of specific examples, but everyone knows the feeling. The single-player equivalent would be doing some kind of crazy sequence break or going out of bounds, putting one over on the developer instead of an opponent, but that usually just breaks everything and isn't actually fun.

Mine would probably be something from a sports game.

A few that come to mind:
Hole-in-one on a par 4 in PGA Tour 3 on Genesis
Pitching a perfect game to clinch the World Series against the CPU in MVP 2005 on PS2

Something like that. From just an achievement perspective, maybe 100%-ing Goldeneye.
