Your subject line reminded me of way back when the first superman TV show was on and it would start out

"Look, look! Up in the sky. It's a bird. No, it's a plane, NO, IT'S, ... IT'S SUPERMAN !"

and out in the schoolyard we would do:

"Look, look! Up in the sky. It's a bird, No, it's a plane. NO, IT'S ... IT'S ... ah hell. It's a bird".

I really like this sequence: Is it really big? > Yes > Are your retinas burning? > Yes > Sun
