"boy meets curl" is the twelfth episode of the simpsons twenty-first season. in this episode, the simpson family visit vancouver where marge and homer compete in the 2010 winter olympics in the mixed-doubles curling team with seymour skinner and his mother agnes. marge's sweeping earns a win for the team and they earn a spot for the olympics. meanwhile, lisa is given an olympic mascot pin and she decides to collect them but her pin collecting addiction goes out of control. marge injures her shoulder in the semi-finals and she is told that she will never sweep again and that the american mixed curling team must concede the gold medal to sweden. lisa buys so many olympic mascot pins that she doesn't have anymore money left so she trades her pearl necklace for a mascot pin from the 1924 winter olympics. bart offers to help lisa with defeating her pin collecting addiction and manages to get back her necklace by tricking the pin vendor with "fatov," who is a phony mascot that was "created" in advance for the 2014 winter olympics but the mascot is really homer's mouth, clipped by bart from his driver's license. when marge is about to leave vancouver, she reveals that she is left-handed to homer and says that she always used her right hand to not seem unusual. she has enough strength to change maggie's diaper and dress her with one hand. they both decide to re-participate in the gold medal game where they defeated sweden and won the gold medal.
