A Texan, a Russian, and a New Yorker go into a restaurant together in London. After being seated the waiter approachs and says,
''Excuse me, but if you wanted the steak you might not get one as there is a shortage due to the mad cow disease,''
The Texan says, ''What's a shortage?''
The Russian says, ''What's a steak?''
The New Yorker says, ''What's excuse me?''
