FedEx is a pioneer in speedy and reliable delivery. For many years its slogan was: When it absolutely, positively, has to get there overnight.

I’ve been reading David Freedman’s Corps Business: The 30 Management Principles of the U.S. Marines, and I learned that FedEx founder and CEO Fred Smith is a former Marine.
Freedman reports an amusing tribute to Smith and FedEx seen on a t-shirt at a Marine base: The U.S. Marines: When it absolutely, positively has to be destroyed overnight.
