My favorite moment from the Olympics - Ahmed Hafnaoui

3 minutes 40 seconds is where the good part starts. I love his reaction. So pure. Gives me chills.

This unknown 18 year old Tunisian swimmer who barely squeaked into the men's final wins gold! He beat out some of the world's best swimmers! He wasn't expected to medal and he had the most disadvantaged lane because he has to deal with the wake off the wall and has one less swimmer to pace off of. A true underdog who is now the fastest 400 meter swimmer in the world! This moment really captures the essence of competition and the Olympics
