A redhead, brunette and blonde were on their way to Heaven.

God told them the stairway to Heaven was 1000 steps, and on every 5th step He would tell them a joke. But, they must not laugh or else they couldn't enter heaven.

The brunette went first and started laughing on the 65th step, so she could not enter Heaven.

The redhead went next and started laughing on the 320th step, so she could not enter Heaven either.

Then, it was the blonde's turn. When she got to the 999th step, she started laughing.

“Why are you laughing?” God asked. “I didn't tell a joke.”

“I know,” the blonde replied. “I just got the first one.”
