Celebration

A young man stumbles into a pub and tells the barman to line up seven shots of Jack Daniels.
He downs them all one after the other.
"Wow!" exclaims the barman, "What was that for?"
"I had my first blow-job" the young man replies.
"Well, in that case a bottle of champagne is on the house" the barman offers.
"That's Ok" says the customer, "If seven Jack Daniels doesn't get rid of the taste then nothing will."
