Snail Beer

A snail goes into a bar and orders a beer. The barman says "Sorry we don't serve snails" and throws him out. A couple of weeks later the snail goes into the bar again and says "What did you do that for?"

The Knot

A string walks into a bar and asks the waiter for a beer. The waiter says, "I am sorry but we can't serve strings here."
The string goes home, ties himself in a knot, and messes up his hair. He goes back to the bar about an hour later, sits down and says, "Waiter, give me a beer." The waiter says, "Hey, aren't you the string who came in here earlier?"
The string replies, "No, I'm a fraid knot."

A Beer And One

A guy walks into a bar with a piece of asphalt under his arm. He asks the bartender for a beer, and one for the road.
