@lordof1 @RogerBW I had to explain the whole 'Bugs Bunny eating carrots is a reference to Clark Gable' thing to a (young) coworker, and he was pretty dumbstruck that, you know, you are probably consuming X which is actually a remake/reboot/reference to Y (older thing).
I will forever point at the fact Xanadu is a remake of a sequel
Pepe le Pew being Pépé le Moko
le Pew was based on Charles Boyer version of Le Moko, but there had been two versions prior to it (that I know of)
Oh I inverted it, it was the Hedy/Boyer then the Casbah. I always think Casbah is first because I like Peter Lorre
