Scene From An Unproduced Film

"Bob" has recently lost his mind, for whatever reason. He has started to make absurd claims, such as being invisible and able to walk through walls. "Joe" is his friend.

Bob (teeth gnashed, highly agitated): "I can walk through walls!!!!!!!!"

Joe: "Dude, no you can't. No one can do that."

Bob (now freaking out): "Yes I can!! YOU'LL SEE!!!!!!!!!!!!!!!!!!"

*attempts to walk briskly through wall. fails and hurts self.*

Joe: "Man, I told you you couldn't walk though a wall!"

Bob (holding head in pain, still freaking out): "THIS ISN'T A WALL!! THIS IS SOMETHING ELSE!!!!!"
