When I signed up at Renderosity originally, I was using jevans (my first initial and last name) at most web sites; when I tried to sign up here with that name, it wouldn't let me use it; IIRC, it was already in use. My standard practice was to add a number to the end of the name and try again. As it would happen, the movie "Bill & Ted's Excellent Adventure" was running on the TV in the living room at the time, and just as I was getting ready to re-submit my user name, they came to the line in the movie where the characters Bill & Ted both chime in with the phrase "Sixty nine, dude!" in response to being queried about their favorite number. I took it as a good sign, and thus my user ID. :)
