I was once playing with some friends on Halo 1. It was 3 vs. 3 on BG, CTF. The two people on my team are moderatly skilled, but are dense in the head. Anyway, I peeked on his screen when I saw he had a sniper rifle and a rocket launcher. He was at the enemy base. He saw a guy, and since he had his sniper rifle out, he shot that at the enemy guy. He fired three shots, then was out of ammo, and the enemy guy started reloading. After he'd finished reloading, the enemy guy killed him.
I asked him, "Why didn't you switch to your rocket launcher?"
He replied, yelling, "I can't play AND think at the SAME time!"
Okay, it's not a question, but it still is pretty funny.
