blonde joke: do blondes go to heaven?

There is a blonde, a redhead and a brunette on the stairway to heaven.

God says, “There are 3,000 steps and I’ll tell you a joke on each 1,000th step you reach. If you laugh you go to hell.”

So they start walking and reach to the first 1,000th step. God tells a joke, the brunette laughs and goes to hell.

Then on the 2,000th step God tells a joke, the redhead laughs and goes to hell.

On the 3,000th step God tells a joke, the blonde doesn’t laugh and proceeds to the pearly gates of heaven.

Suddenly, she bursts out laughing.

God asks, “what are you laughing about?”

She replies, “I just got the first joke!”
