One man looks at the prices and says: “These beers are too pricey, With the money I have I can only buy one beer.” The other gets an idea. So they buy a sausage and go back to the bar.
After a couple of bears one man puts the sausage in his pants and the other starts sucking it, the bartender kicks them out of the bar without them having to pay.
They do this all night and get kicked out of 7 bars, at the 8th bar one man says: “this sausage is getting sour” the other replies with “The sausage? I lost that thing at the third bar”
