Ben and Tim want to go drink in a bar
Problem is, they have no money. "No problem" says Ben, "I have a cunning plan. Take this sausage and put it in your boxer. We go into the bar, drink a couple of beer and when they come with the tab you open your pant and let the sausage out. I go down on it and they will kick us out and we won't have to pay."
Tim agrees, takes the sausage and off they go in the bar. They drink, and after two or three rounds they see the bartender coming with the tab. So Tim opens his trousers and shows part of the sausage, and Ben goes to town on it. Bartender is not amused and kicks them out.
Happy that it works they go to the next pub. Same game, they drink, have fun and when the tab arrives they play dip the sausage and get thrown out.
This goes on for a couple of bars, until after one throw down (or throw out) Ben shakes his head and tells Tim "Sorry old friend, I can't take any more beer or sausage tonight". Tim looks at him and answers "You have it easy, I lost the sausage three bars ago..."
