Everywhere you go you'll find athletes with weird warm-up rituals.
For Simone Biles, it is drawing a dollar sign in chalk that gets her going for gold.
The 145cm tall gymnast took home gold in five different categories, proving you don't need to be massive to make your mark in the Olympics.
"You see, everybody puts their line on the beam, so I can never tell which one is mine. So, I put an 'S' on it, and it happens to turn into a dollar sign. People think I do it on purpose, but I don't," the Pittsburgh Post-Gazette reported her saying.
Intentional or not, Biles' piece of showmanship didn't go unnoticed.
