My nickname in high school was Lord Nooklious... I get a warm fuzzy feeling just seeing it spelled out again.

Mad Mojo Monkey came out of a music project in college.

I play guitar/bass and sing. My roommate had a accordion and was an excellent song writer.
We wrote a couple of songs and jokingly called ourselves the Mad Mojo Syndicate.
I had a habit of playfully calling my friends a monkey whenever they did something silly.
Eventually, the name Mad Mojo Monkey became my moniker.
