A golfer invited a minister, a doctor and an engineer to play golf at his club. After a few holes, one guest said "That foursome ahead of us is really slow. They're all over the fairway, they're in the rough, four-putting holes...couldn't we ask to play through?"
The host replied "No, we don't like to do that. Those guys are blind. They have a special pro who helps them line up shots, and our club lets them play free."
The minister said "Why that's marvelous. What courage! I'll ask my congregation to pray for them...maybe we could get a miracle."
The doctor said "Well, maybe I can beat that. I know an ophthalmologist who's having good luck with some experimental surgeries...maybe he could help."
The engineer scratched his chin for a moment and said "Couldn't they play at night?"
