When I first started playing MOH I wanted a unique name. I always read the Funky Winkerbean comic strip every Sunday when I was a kid and even as an adult I still enjoyed it. So, I became FunkyWinkerbean but once COD and other games came out, the name was too long. For a while I was Dr. Funky but everyone just called me Funky so eventually I dropped the Dr. and just went with Funky. The current iteration of FUNky is because I used to run with a lot of interesting people and we had some awesome parties. Everytime I arrived at a party someone would always say Steve is here! Now we're going to have fun!
So that is the Readers Digest version, You can't spell Funky without FUN.
