TV's Frink said:

Since this is now the "explain your nick" thread, mine is a combo of TV's Frank from Mystery Science Theater 3000 and Professor Frink from The Simpsons.

And I've been looking for an opportunity to tell you how awesome your screen name is:

Your screen name is awesome.

Mine is from a group my friends made in high school, back when everyone was obsessed with GoldenEye 64. We all picked numbers, I got 005. When I wanted to change my lame first.last@juno.com email address (to give you an idea of how long ago this was), it hit me to spell it out. I've used it for everything ever since.
