Give Me A Double

So this guy walks into a bar and says, "Gve me two beers."
The bartender obliges him.


The guy looks into his wallet and says, "Give me two more beers."


So the bartender gives him two more beers. The man went on like this until he
had put down ten beers, and keeps on going in his wallet and asking for two more
beers.


So the bartender asks, "What's in your wallet that you keep looking at?"


So the man opens his wallet and says, "The more I drink, the prettier my wife
gets."
