Miscommunication
Mood:  d'oh
The Greek capital of Athens once hosted a football match between a Greek team and a team from China.  Before the match, music began playing over the stadium's sound system.  Thinking that it was the Greek national anthem, the visiting Chinese players all stood to attention.  The Greek players and spectators knew that it was not their country's anthem, but they too sprang to attention, assuming that it was the Chinese anthem.  Then, as everyone continued to stand to attention, a voice boomed over the speakers praising a brand of toothpaste.  The music had been part of an advertising message.
