Fact or Fiction: When Chuck Lorre originally created The Big Bang Theory, the boys were dominated by a nasty neighbor named Katie.

Fact! Chuck Lorre told Watch magazine's Jim Colluci that a year before The Big Bang Theory was picked up by CBS, the first pilot had a female character named Katie. She manipulated the guys. "It was like shooting fish in a barrel. It didn't work," Johnny Galecki told Colluci. The problem was that Sheldon, Leonard, Raj and Howard were and are essentially innocents and without maliciousness. The idea of a woman taking advantage of their innocence was not only mean, it wasn't funny. The writers went back to the drawing board -- so to speak -- and, thus, the character of sweet, gentle Penny was born.
