This has been the first Olympic Games where social media has been a prominent presence. So naturally the best way to take advantage of this is to put your horrible racism on display for the world.
Swiss footballer Michel Morganella was expelled from the Olympic Games today after referring to the South Korean squad that had just defeated his team as "a bunch of mongoloids" on Twitter.
Morganella's coach was appropriately outraged:
"He discriminated, insulted and violated the dignity of the South Korean football team and people."
But don't worry, because according to Fifa president Sepp Blatter, "there's no racism in football."
