I explained this on the username homenode but I'll retell the story here too...

feloniousMonk is my homage to Thelonious Monk. He was one of the creators of BeBop, a new breed of jazz.

And why not just use his name? Well, when I was a child and heard his name I thought people were calling him Felonious. So it stuck with me.

My second choice was GregorMendel but tho I like genetics I'm not that fond of peas :-)

-felonious--
