Barman 1: Who's that cool motherfucker ?
Barman 2: Don't know, but last night he came in smoking a joint, asked me where the nearest brothel is, drank a whole bottle of whisky, did some coke off Mia's tits, fucked her, buggered her and left. I think he's an EFL teacher.
Barman 1: Shit, that's so cool. I wish I was him. Oh, look- he's just knocked out two of the bouncers with one punch.
