Friendly live sit-n-go at my buddy's house years ago with about 6 players total. Extremely small buy-in ($5 - hey, we were barely out of high school!). I didn't want to play at all in the first place and was in a piss-poor mood, so I call my buddy's preflop raise with 25o a few hands into the game. Flop comes A38. He bets big. I call. Turn comes J, he bets big, I call. River is a 4, he goes all-in, I call. He flips over AA, I flip over my straight. He splashes his chips all over the table in front of me despite having some chips left over, starts yelling, then turns the lights off in his house and goes to his room for the rest of the night.
Late night game in a casino poker room - only about 2-3 tables going, $1/$2 NL. A man walks in with a woman (pretty sure she was a hooker based on their behavior and her dress), leaves her at the bar, and sits down next to me. I can immediately tell he's HAMMERED. He loses a couple pots, goes on full tilt, and starts raising outrageous amounts without looking at his cards and while acting tough.
One hand, he goes "I'll just call this one." I call with AJ, flop comes AJJ. He immediately goes all-in, I call, he busts. He buys in again, and with a pompous tone of voice, says "I'm not even looking at my cards - ALL-IN!" Everyone folds, I look down at AA, call, he has trash and busts again. I ended up taking $200-$300 from him in under 30 minutes, and another guy at the table ended up taking $400 from him in the same period of time. Unfortunately he wasn't buying in for the max amount.
