I've always liked "Sick my Duck" too. And believe it or not, I like "Goober McFly" because as he once explained it, he took two of the nerdiest fellows in popular culture and combined their names. And that just seems so appropriate for him.
I have always been a fan of the joke name, like Amanda Huginkiss, Hugh G. Rection, and Harry P. Ness. I think there is a Hugh G. Rection on this board, isn't there?
