I shudder to post this but it was quite funny -
Guy walks into a bar and says "bartender! give me 6 shots of tequila"
The bartender looks at him and says "6 shots of tequila, what's the occasion?"
the guy says "I'm celebrating my first blow job"
Bartender says "congratulations, well let me give you the 7th shot on the house"
guy says "Thanks, but if 6 shots doesn't get the tast out of my mouth, i don't think anything will"
