A pig walked into a bar and asked, "Do you serve root beer?"

The bartender said he did.

"I'd like one, please," the pig said.

After the pig had finished, he asked to use the rest room. After the pig left, another pig came in and asked for two root beers. This pig then asked for the rest room just like the first one had.

Then two more  pigs came in. One ordered three root beers and the other four. They, too, used the rest room. When a fifth pig came in, the bartender said, "Let me guess, you want five root beers."

The pig was shocked. "Why, yes. Yes, I would."

 When he was done, he started to walk out. The bartender was confused.

"Hey, don't you want to use the rest room like the other four pigs did?"

"No.... I'm the fifth little piggy.....

........"I'm the one who goes wee-wee-wee all the way home."
