Inspector Gadget

Question: When Inspector Gadget is lying on the table with the Claw watching over him, Gadget says that Claw will never get away with this. Then Claw says, "I think someone's been watching too many Saturday morning cartoons", and then everyone looks up at the camera confused/surprised. Can any one explain what the joke is here?

Chosen answer: The joke is that he is referring to the "Inspector Gadget" cartoon, in which the Claw never got away with any of his schemes.
