An Englishman, an American and an Irishman

An Englishman, an American and an Irishman walk into a Bar.

Each orders a double scotch.

Through a stroke of misfortune, a fly lands in each of their drinks.

The Englishman calls the waiter, points out the fly, and gets his drink returned.

The American looks around a while, ensures no one is looking, takes the fly out with a pair of tweezers and keeps drinking.

The Irishman picks up the fly with his fingers and with his blood boiling, screams at it:

“Spit it out, you bastard! Spit it out!”
