A guy walks into a bar and orders a double Chivas neat
(That means Scotch whiskey with no ice)
The bartender serves it and the guy just slams it down. "Another," he wheezes.
The bartender decants another and the guy slams that down too. "One more," he stammers.
The bartender pours the third and the guy again quickly just slams it.
"Hey buddy why are you drinking like this? What's the occasion?"
"My first blow job!"
"Well," says the bartender, "The next one is on me then!"
"Nope." says the man. "If three Scotches won't take this taste out of my mouth, a fourth won't either."
