A little pig, upon entering a bar, walks up to the bartender and asks for 10 glasses of beer. Upon finishing the last of his beers he gets up, pays the bartender, and then asks him for directions to the bathroom.
Just as the first pig is leaving, a second one enters the bar. He too walks up to the bartender and asks for beer, but this pig asks for 20 glasses instead of 10. Upon finishing the last of his beers he too gets up, pays the bartender and then asks him where the bathroom is.
The 2nd pig leaves, and in comes a 3rd little pig. He walks up to the bartender and asks for 30 beers. Then upon finishing the last of his beers, he too gets up, pays the bartender and then asks where the bathroom is. By this stage the bartender has begun to notice a pattern.
In comes pig No. 4. As soon as the bartender spots this pig he begins poring 40 glasses of beer. The 4th pig drinks all 40 glasses as fast as if his life depended on it. Then, when he had finished, he pays the bill and asks the bartender for directions to the toilet.
The bartender was astonished that pigs could drink so much, yet he was even more surprised when a 5th little pig walked in and asked for 50 glasses of beer. The bartender, who’s completely astonished, complies and hands the pig his beer before remarking “I suppose you’ll be wanting directions to the bathroom like the others”. To which the pig responded “Oh no thanks. I’m the 5th pig, i go ‘Wee Wee Wee’ all the way home”.
