Engineering360: "10 Jokes that Only Engineers Will Understand"

A pastor, a doctor and an engineer wait for a particularly slow group of golfers. The engineer fumes, "What's with these guys? We've been waiting for 15 minutes!"
The pastor says, "Hey, here comes the groundskeeper. Let's have a word with him."
"Say, George, what's with that group ahead of us? They're rather slow, aren't they?" the doctor asks.
The groundskeeper tells them that the other golfers are a group of blind firefighters who lost their sight saving the clubhouse from a fire and that they come and play for free whenever they want.
The group is silent for a moment.
The pastor says, "That's so sad. I will say a special prayer for them tonight."
The doctor says, "Good idea. I'm going to contact my ophthalmologist buddy and see if there's anything he can do for them."
The engineer says, "Why can't these guys play at night?"
