Many years ago on the Armed Forces radio network in Europe, the programming director sent a note to his assistant to do some special programming for Veteran's Day, so the staff could take the day off.
Half way through Veteran's Day the program director turned on the radio to see how things sounded, but was horrified to hear graphic talk on Venereal Disease!
It turns out the note he gave to his assistant told him to do "V.D. Programming."
