On day a redhead, a brunette, and a blonde were on their way to heaven.

God told them the stairs to heaven were 1,000 steps and on every
step he was going to tell them a joke. If they laughed they would not
be able to get to heaven.

So the redhead made it to the 45th step and laughed.

The brunette made it to the 200th step and laughed.

But the blonde made it to the 999th step and laughed even before god told his joke.

God asked "Why did you laugh I haven't even told the joke yet"

The blonde said "I know I just now got the first one!!!"
