Dutch on the stream told some funny stories about this dude today:
Raymond Davis once saw a shitfaced Dan Heimiller being dragged into a room by 3 girls. Next day, Davis found out the bitches took Dan's entire roll. They eventually found the girls and charged them, last Dutch heard.
There's also another story where Heimiller and Gavin are playing in a 2/5 game in the Tropicana Poker Room, when Jamie Gold was hosting at the time after winning the WSOP. Gavin is drunk and shitting on Heimiller constantly during the game: calling him a nit, telling him he never gives action, and is overall boring and sucks at poker. So, Dan steps away from the table, and goes gets a slice of pizza. While Gavin is in the middle of a hand, Dan goes behind him, takes off his fedora, and drops a slice of pepperoni right on Gavin's dome. Gavin wails like a beached whale, and they throw blows and get 86'd from the Trop (Jamie eventually got them back in).
