I heard this joke a long time ago and I've tried getting laughs ever since. I swear I won't give up trying.

A priest, a surgeon and an engineer are going golfing on a Saturday. The golf club owner says the court is unavailable - on Saturdays the golf course is in use by a group of firemen who lost their eyesight while rescuing golf club members out of the club house a year back. The surgeon exclaims "that's awful! I'll arrange a fundraiser, maybe we can help improve their eyesight." The preacher folds his hands and states "my communion will include them in our prayers." The engineer is silent for a moment, then asks: "Can't they just play at night?"
