An Irishman, an American, a Jew and a Greek all die...

When they get to Heaven, they're given the chance to go back to Earth and give it one more shot.

"But whatever sin you committed most in life, you must not even think once of committing it again," they're told, "Or you'll be right back up here."

All four end up together back on Earth, and start walking down the street, talking about the experience and what they think their worst sin was.

They pass a bar. The Irishman looks in, gets a greedy look on his face, and *poof* disappears.

They pass a fast food restaurant. The American looks in, starts drooling, and *poof* he disappears, too.

The Jew and the Greek keep walking, joking at their friends' foolishness. The Jew sees a dollar bill lying on the street. He bends over to pick it up, and ...

*POOF* they both disappear.
