Bar Fly

An Englishman, a Scotchman, and an Irishman are sitting at a bar, each with a beer in front of them. All of a sudden, three flies zoom in and land right in each of the beers.

The Englishman pushes his beer away in disgust, gets up, and leaves.

The Scotchman simply pulls the fly out, tosses it on the ground, and continues drinking.

The Irishman however, pulls his fly out and begins beating it against the counter while shouting, "Give it back, give it back!"
