A preacher, a psychologist, and an economist went golfing one afternoon.  After a few holes, they were stuck behind two golfers who were playing extremely slowly, hitting balls in the trees, the water, and just about everywhere else besides the fairway.  Finally, after a few holes of this, the threesome became upset and started making derogatory comments loudly enough that the twosome in front of them could hear.

Eventually, one of the caddies for the twosome went back and explained that the pair in front of them were retired firefighters who had been blinded while racing into a burning building to save nine children, and that the three men should have some sympathy and compassion.  Of course, after hearing this, the threesome felt terrible about the whole situation.

The preacher said, "This is terrible, here I am a man of the cloth, and I've been ridiculing these poor men."

Then the psychologist said, "This is terrible, here I have spent my whole life trying to make people feel better about themselves, and I have been making demeaning comments within earshot of these poor blind men."

Finally, the economist said, "This is terrible, these guys should be playing at night."
