Yeah but... skinless bananas?!
He did invent the skinless banana so you can never take that away from him!
The only snag with that one (aside from their, afaik, non-availability) is that the comedy potential is reduced. And also, banana skin has always been pretty user friendly; the obvious candidate for a skinless fruit is an orange... and I believe you can actually purchase those skinless (in a plastic container).
So I guess I have to concur... yep, the guy's an idiot! ;-)
