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.
