A school talent show

During a performance for the high school talent show at the local theatre, a hole was cracked in the stage floor. Subsequent acts managed to just avoid the hole until little Freddy, 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, Freddy! It's just a stage you're going through!"
