Anyway ,you know how the Irishcan drink and soon there is a massive bill for the alien to pay. The bar tender is eventually out of booze and nervously hands the alien the bill for a vast amount of money. " Have ye enough t'pay yer bill" asks the bartender ?
No problem says the alien , produces a weird looking piece of metal and asks " have you got change for 50Zork"
So an Irishman , a cow and three penguins walk into a bar. There is an alien sitting there and he is paying for all the drinks.
