An assembly line worker at Chrysler was picked for jury duty, but asked the judge to excuse him. "This is a very busy time at the plant, Your Honor, and I need to be there."
"Oh, I see," the judge said. "You're one of those folks who think you're indispensable, that Chrysler can't get along without you."
"No, sir, not at all," the worker replied. "I know they can do just fine without me, but I don't want them to find that out."
"Excused," the judge said.
