There once was pirate captain who, whenever it looked like a battle would be imminent would change into a red shirt. After observing this behavior for a few months, one of the crew members asked him what it meant.
"It's in case I get shot. I don't want you crew members to see blood and freak out."
"That's very sensible, sir." At that moment, the crew member spotted eight hostile ships on the horizon. The captain all of a sudden looked very concerned.
