Whos the Smart One Now?

Once there was a blond, a red head, and a brunette. They had to tell a joke in order not to go to hell. So the red head goes first: "What do you call a boy going to jail? A Micheal Jackson lover." (not that funny) So she goes to hell. Then the burnette says: "What's the difference between your mama and the blond's mama? The blond's has a bigger chance on giving it up and yours doesn't need any." (not that funny either) So, she goes to hell as well. Finally, the blond says: "Knock-knock! Who's there? God God who? Godzilla!" (not that funny) But, the blond gets in! Why? Because, she used God and didn't notice it.
