This is an extremely random idea that came to me as I noticed that the Japanese Womens team had won the Football (Soccer to Americans) World Cup on penalties. It was another silly idea that just had to be done. 
Tai and the boys Soccer team have made a mistaken bet... And they must now pay the price to the winners - the girls Soccer team...
(The specific bets, by the way, for those curious, was for the boys to dress as girls if the women's team won the final, and for the girls to wear their swimsuits the whole day if they lost.)
