I have to admit, I wouldn’t have come up with this:
Suppose Ferris Bueller never actually existed.
Most of your fictional characters didn’t, but okay, we’ll play along.
The parade float. That’s just silly. And Ferris never gets in trouble. He never has any actual plans for staying out of trouble, nor does he show good judgment or skill at staying out of trouble, but the boom is never lowered on him. The reason is, he isn’t there; he lives inside Cameron’s head. Cameron’s just a lonely bored guy with nothing going on, so he imagines everything.
I don’t want to talk about Fight Club here, but that sounds awfully Tyler Durdenesque: see, for instance, this MetaTalk thread.
(You’re still here? It’s over. Go home. Go.)
