The representatives of the world's big beer-brewing companies are meeting for a conference. At the end of the first day, a few of them retire to the hotel bar to have a quick drink.
The first representative, an Aussie, steps up to the bar. "Everybody knows that Australia brews the best beer, so make mine a Foster's, mate."
The second, a Dutchman, steps up. "It is known far and wide that the best beers come from the Netherlands, so make mine a Heineken."
The third, an American, steps up. "Hell, everybody knows that Americans make the best beer, and I brew the King of them all, so make mine a Bud."
The fourth, an Irishman, steps up to the bar. "I'll be having a cup o' tay, thank ye."
The others stare at him in amazement. "Aren't you going to have a Guiness?"
"Thanum an Dhul, what d'ye take me for? If you ain't drinkin', I ain't drinkin' neither!"
