There was 3 girls, a blonde, a brunette, and a red head. and they found a pyramid¹. they read a tablet² that said "this is the pyramid of 100 steps. if you
get to the top of it, you will get what you've wanted all your life. but be warned³, every 5 steps a person will pop out and tell a joke, and if you laugh, you can never try again."

so the brunette gets to the 5th step and laughs, so she could never try again.

the red head got to the 20th step and laughed, so she could never try again.

then the blonde got to the 99th step and laughed. then the guy who was going to tell the joke said "why did you laugh, i didnt tell the joke yet." then the blonde said "i know, i laughed because i just got the first joke!"
