I've recently had an insight: sandwiches are just like gorillas.
Uh, by which I mean that when I'm reading a comic book, seeing a character with a sandwich enhances the experience for me just as much as is I had seen that same character fighting a gorilla. Now, I don't know if this is a universal condition or if it's just me, so I'm going to try to gather some evidence and present my case. It may take some time. In the meanwhile, I'd like to give you a couple of situations to look at:
Case No. 1: The Ray Issue 14, The Ray bursts in on Vandal Savage.
Case No. 2: 52 Issue 46, Steel and Clark Kent burst in on Lex Luthor.
Now I ask you: could these panels have been any better, no matter what Savage/Luthor's response, without the presence of a gorilla? Maybe, but it would have been pretty rough going. The sandwich, my friends. The sandwich.
I realize that this is hardly conclusive proof, but every movement must start somewhere.
