It was right after Halo CE came out, I was playing co-op at the part of the mission Halo where you have to activate the hard light bridge, and as the Elite Major turned the corner in the narrow access hallway, and I panicked and threw a sticky at him. He was stuck in the b*lls (or whatever elites have down there) and as it stuck he screamed at me and blew up. My friend and I started laughing so hard that we were killed by the same grunt that only had a plasma pistol. That, or when I played Halo CE and had to use a DDR pad as a controller because it was four player and we only had 3 controllers.
