Dan houser proabably drinks whiskey while working, this explains his asshole act to employees. Also, he proabably snorts off cocaine from a bowie knife screaming ''BULLOCKS!!! GTA IS THE GREATEST OF ALL TIME! I MADE f*ckIN' 1 BILLION DOLLARS OUT OF V!'' *says with a english accent, and snorts off cocaine again*.
This somehow reminded me this (except for coke and English accent):
"Nobody moves video game in North Valley, but me b*tch!"
