Back when I was in USAF one of our more humorously cynical officers got custom made Christmas cards one year. The cover art was similar to the USAF logo / seal with some snow piled atop like the Sherwin Williams “paint the globe” logo. It also had some snowy pine trees nearby and an airplane.
The pre-printed interior said “Have a Military Christmas and a Professional New Year!”
Massive smirking all around us junior officers. Some of the brass were Not Amused.
