Mick and Paddy get off a ship and head for the nearest bar. Each one orders two whiskeys and immediately downs them. They then order two more whiskeys and once again quickly throw them back. They then order another two whiskeys apiece.
Paddy picks up one of his drinks, turns to Mick and says, "Cheers!"
Mick turns to Paddy and says, "Hey, did you come here to bullshit, or did you come here to drink?"
