Four golfers (a doctor, a lawyer, a priest, and an engineer) are stuck behind a really slow group of golfers. They start to get frustrated, so they call up the course's pro.
"Hey, how come you're letting guys like this on the course? They're hitting their balls all over the place, spending way too much time lining up their putts, always in the sand traps...and they don't see us trying to play through!"
The pro says, "Well, you see, last year there was an awful fire at the clubhouse. And these four firemen were injured fighting the blaze. They all lost their eyesight! Well, since they did so much to save us, the least we can do is let them golf here whenever they want to."
The doctor says, "Oh, that's horrible! You know, I know a lot of good eye doctors. I'm sure they can do something to help restore their sight."
The lawyer says, "Hmm, I wonder if their masks were defective. I can probably file a huge lawsuit against the manufacturers. Pro bono!"
The priest says, "They are saints! I will pray for them and use their story as an example of courage and selflessness in my next sermon."
The engineer asks, "Why don't they play at night?"
