I've been blown up by my own tripmine more times than I would care to admit. There have also been a few Golden Guns where I've missed every shot. Jumping so high that I tether a rafter or obstruction and hearing the opponents below me laugh as they welcome me to the Thunder Dome. Forgetting I was running Defender, running on to a flag thinking "aww yeah I'm going to smash all these fools!" Popping a bubble and promptly getting beat to death my 4 enemies.
