While working as a volunteer at our local Boy Scout Council office, one of the professional staff -- who was wearing street clothes instead of her usual uniform -- was talking about the NATO phonetic alphabet.

She said that she had learned it some years ago and proceeded to recite it. "Alpha, Bravo, Charlie, Delta..."

But, when she got to the letter "U," she stumbled and asked for help.

I offered a hint: "What AREN'T you wearing today?"

"Underwear?" she replied.
