The women's gymnastics final was an exciting event full of surprises - and that's discounting the falls and tumbles.
Team USA won the gold medal, powering ahead of the competition early on and finishing with Simone Biles' absolutely incredible floor routine.
Twitter users just couldn't believe how good the Americans were.
Another shock was the Chinese athletes who looked much younger than their actual age.
They took the bronze medal, behind the Russians who took silver.
What wasn't a shock though was the fact that most people didn't really know what was going on.
Tough luck to Team GB, who came fifth after a fantastic effort.
