It's the PBR farts that you have to watch out for! For the topic at hand, I think once a few beers have been consumed one becomes more tolerant of the cheesy storylines and dialogue between characters.
Don't know about you Jim but the only thing on my mind after a few pints is getting my cock sucked. I think RPGs require an inherit mazochism, especially when you factor in all the cheese. On the contrary, being drunk is about pure fun, the sort that kids have on Ritalin.
