Blue Man Group
I mean these guys...
You cannot seem to go anywhere here without seeing the people who are building, fixing, cleaning, painting and maintaining everything....wearing blue jumpsuits. Seriously, did someone accidentally order 1,000,000 of these, and nobody said anything because they didn't want to rock the boat?
One of the Navy officers here referred to them as "Blue Man Group" when they were working on part of our HQ. I rather liked the name, and it has stuck.
