I am a former Marine. During WWII in the battle of Belleau Wood the Germans called us Teufelshunde..."Devil Dogs." A moniker that is accepted by calling out to other Marines.
There are so many "Devildogs," when I singed up for my e-mail account, I changed it to Devildawg, and bingo! JJ are my initals. Some people call me JJ.
In the Marines, they called me Buffalo Bill. I used to do this hilarious Buffalo Bill impersonation over the squadron radio, just to keep things frosty.
Maintenance Control, was so uptight about it...
PRECIOUS....."Put the lotion in the basket!"
