In the early 1950's, Denver architect Temple H. Buell, often called the Father of the Mall, conceived of and built one of the first shopping malls in the U.S.: the Cherry Creek Mall.
A man walked into a gift shop that sold religious items. Near
the cash register he saw a display of caps with "WWJD"
printed on all of them. He was puzzled over what the letters
could mean, but couldn't figure it out, so he asked the clerk.
The clerk replied that the letters stood for "What Would Jesus Do?", and was meant to inspire people to not make rash decisions, but rather to imagine what Jesus would do in the same situation.
The man thought a moment and then replied, "Well, I'm
sure Jesus wouldn't pay $17.95 for one of these caps."
