Bloke walks into a bar, and orders 12 shots of whiskey. To the bartender's surprise he downs the lot and pays up. "What's the big occasion?" asks the bartender. "I'm celebrating my first blowjob" replies the bloke. "Good on you, son. Have another whiskey on the house." "No, thanks," replies the bloke, "If 12 didn't take the taste out of my mouth, one more won't do much."
