A skeleton walks into a bar and says to the bartender, "give me a beer and give me a mop."
A sandwich sits down at the bar and the bartender says, "sorry. We don't serve food here."
A snail crawls (slithers) up to the bar and the bartender picks it up and gives it a 'twink with his finger and out the door it flies. About a year later, the same snail slithers back up to the bar and says "Hey! Why'd you do that?"
How about the one where an big muscular Irishman walks into a bar carrying a humongous pig under his arm.
"Good Grief," says the barman, "that's a magnificent beast, where did you get him?"
The pig looks up and replies "I won him in a raffle!"
