During a time when i was spying on someone, i left my computer to get orange juice, and to surprise me when i got back. A box around me. It was only like 5 seconds. And i got a box built around me? I was flattered.
...For mine, mah avatar says it all :D
When I got blown by a mini-nuke and got flung over the map doing constant highspeed barrel rolls.
My funniest moment was when I smacked into the wall with Jet Boots.
