Switching Goals

Sam (Mary-Kate) is the sporty, less-popular one, while Emma (Ashley) is the boy and fashion-obsessed one. Here, the twins sign up for their dad's soccer team. However, Emma is picked first out of pity for her dad's Hurricanes team, while Sam is shafted into the loser-ish Buzzards team. So, to help each other out, Sam and Emma trade places with each other to play on the opposite teams... until their mom finds out. (imdb)
