Another dirty joke

A guy walks into a bar, sits down and tells the bartender “Pour me 10 shots of tequila straight up”.

The bartender looks at him and obliges. Pouring all ten shots, the guy pounds them all, one right after another.

The bartender looks on in amazement and asks “Dude, I gotta know what you’re celebrating?”

The guy replies “I just had my first blow job”

Bartender says “well geez, here’s another shot on me”

Guy says “if the first 10 didn’t wash the taste out of my mouth, the 11th one’s not going to help”.
