Pearly Gates
A blonde, brunette and redhead passed away in a car accident.

They arrive at the pearly gates and they are told they will be told a joke every 10 steps and they must make it up 100 steps. If they laugh they will not be able to get in.

The brunette went up 30 steps and laughed. The redhead went up 50 steps and laughed. The blonde got up all the way to the top and then started laughing hysterically.

When asked "Why did you laugh when you got to the top?" The blonde replied, "I just got the first joke!"
