"superstitious, eh?"
"oh, a vi-sci kid..."
it's a spoonerism/brooklynism of 'sci-fi', slangy kind of in the vein of 'oh you kid' or 'quiz kid'... i love those psychedelic moments in the really old shorts (don't get poisonal!), like listening to Popeye in the Fleischer cartoons muttering between the lines, or translating bowery boys etc...
