"This little Piggy!" joke

A pig walks into a bar and orders a beer. After drinking it, he hops off the bar stool, pees on the floor and leaves.

Another pig comes in, drinks his beer, pees on the floor and leaves.

A third and forth piggy come in and do the same exact thing.

Finally, a fifth piggy comes in to the bar and orders a beer. After finishing his beer, he gets off the bar stool and begins to walk out the door.

Before reaching the door, the bartender yells - "Hey Pig... aren't you going to pee on the floor like the others?"

To which the pig replies - "No you idiot! Everyone knows that the last little piggy goes WEE WEE WEE - all the way home!"
