Well I was a submarine sailor in the US Navy and we called ourselves bubbleheads which is really a durogatory name surface warfare pukes gave us, but we embraced it just to piss them off. I dropped the extra "B" because IRC chat handles used to only allow 9 characters max back in the early days. It also gets people to ask why it's misspelled all the time and I get to tell them this story.

Haha, Spent many a day/night in Groton during offcrew... on and off for about 4 years and 6 Strategic Deterrence patrols on the USS Andrew Jackson and one on the USS Will Rodgers. Part of the 44 for Freedom fleet and a Cold War veteran from the 80's. It is unfortunate that the Russians blew up Chernobyl in '86 but thats the reason I work writing code for a large national bank instead of working as a nuke reactor operator for the power companies. I got out of the Navy a few months after that and the civilian nuclear power industry was in a massive decline due to the accident. Stayed away from nuclear power ever since and now kind of glad I did. Radioactivity is not something you really want to be near on a long term basis, especially when being done for "profit" and running at 99% power all the time. The Navy knew how to do nuclear well, but even then they were not perfect.
