…….are trying to enjoying a round of golf. Ahead of them is a group playing so slowly and inexpertly that in frustration the three ask the greenkeeper for an explanation. “That’s a group of blind firefighters,” they are told. “They lost their sight saving our clubhouse last year, so we let them play for free.”

The priest says, “I will say a prayer for them tonight.”

The doctor says, “Let me ask my ophthalmologist colleagues if anything can be done for them.”

And the engineer says, “Why can’t they play at night?”
