Guy walks into a bar and catches the barman's eye. Double whisky! he shouts. The barman pours it, serves it and GULP, the guy knocks it back in one go. Are you alright, mate? asks the barman. Sure, says the guy, I'm celebrating - another double whisky! Barman serves it, guy grabs it and downs it in one again. What are you celebrating? asks the barman. Aaaaahhhh, says the guy can't tell you - it's a secret. Another double whisky!. The barman serves it to him, the guy grabs it and downs it in one. Come on, says the barman, you'll be pissed in a minute and tell me anyway - what're you celebrating? Oh all right, says the guy, looking around furtively, first blowjob! Ohhhhhh, well done my son! beams the barman, here, have one on me! The guy peers at the drink, thinks, sniffs. No thanks, he says, if three won't get rid of the taste, nothing
