In those old Silver Age stories, just what is it with Barry Allen and gorillas? Sure, Gorilla Grodd is an arch-enemy of Barry's, but just mention gorillas around Barry and he practically loses his head over it. Case in point:
Great Scott, Barry! Do you think it could be a ... a ... gorilla?!
He's gonna be really disappointed if it turns out to be just a chimpanzee.
Love the hat, by the way.
