re: #158 Dr Lizardo
That gag was inspired by Seth MacFarlane being freaked out by that album cover when he was a little kid.
It certainly was one of the more unique album cover artworks of the era. IIRC, it was an homage to a cover of an edition of Astounding Science Fiction from the 1960s.
Did they not have to coax Kelly Freas out of retirement to do that cover? (Or am I confusing that with the Cars getting Alberto Vargas to do Candy-O)?
