A Man Walks Into A Bar [NSFW]

A man walks into a bar and orders three shots of the establishment's finest whiskey.

"Whoa, buddy," says the bartender. "You must be celebrating!"

"Yes I am! I'm celebrating my first blowjob!"

"In that case," responds the bartender "the fourth one is on me"

"No thanks. If the first three don't get the taste out of my mouth I don't think that the fourth one will either."
