From what I can quantify, Mary Kate and Ashley are interacting with soccer for the 3rd time in their lives. The first 2:
1) The classic “Wrong Way Tanner” episode of Full House, when Michelle scores a goal in the other teams net. This exact scenario also happened to me as a child, but John Stamos was NOT there to comfort me.
2) The 1999 made-for-TV movie “Switching Goals”
And now, the third - their contemporary line Elizabeth and James’ World Cup t shirt collection.
