I will misspell alot but...

there was a movie called "The End" and it had Dom Delouise in it and he did a skit of being a schizophrenic (sorry I am killing the spellings)..... and he did the same Wayne just did.

It was a classic !

While Wayne may, or may not, remember the skit in the mental hospital...I think Wayne saw it at some point.

"Vanishing Point" was a great flick, too....not related to this post, though. lol.
