During the performance of a high school drama class at the local theatre, the stage floor was damaged resulting in a distinct hole.

Subsequent acts managed to avoid the damaged area until Billy, juggling bowling pins, accidentally stepped through the hole up to his knee.

He apologized to the audience for his clumsiness. But a heckler in the back of the theatre shouted:

"Don't worry, Billy! It's just a stage you're going through!"
