I'm almost certain that Hatton would destroy Oscar in a drinking contest. A coke snorting contest? Nowwww we have a battle!
Hoya is passed out in a French maid outfit with a dildo in his ass long before Hatton is finished his drinking
My old man was Polish and I couldn't outdrink him until he turned 80, and even then it was very close. And I'm a bloke who can confidently smash 3/4 bottle of spirits or half a slab of an afternoon/ evening and still function. Even just before he died, he could almost finish a full bottle of whisky of an evening, even if that evening finished with him on the floor. Slav livers, made of stone.
