Dumb Blonde Joke No.621

There's a blonde, a brunette and a redhead. They are all dead and want to go to heaven but there are 99 steps to heaven. On each step they are told a joke and if they don't laugh they can go up to the next step. The redhead made it to the 20th step and the brunette made it to the 50th step. The blonde was on the 99th step about to be told the last joke and she burst out laughing. The joke teller says "Why did you laugh your on the last step?!" The blonde replied "I just got the first joke."
