From a recent conversation with my 6 year-old son:
The Boy: (sounds Very Serious) Daddy? Me: What's up kid? Did you know there was a purple Hulk once? Really? Yes. He was made in the Golden Age by DC Comics, but they gave him to Marvel later. That's amazing! How come I never heard about this? What was his secret identity? (Thinks about it) Jimmy Olsen. Jimmy Olsen?!? Yeah. He was the Hulk before he knew Superman. Gregory, this is HUGE. Do you mind if I share this with my readers? (An excited jumble of words amounting to): I insist that your readers write and produce a movie about the Purple Hulk! (Runs away roaring) Me: I'll take that as a yes!
