After spending a day on the weekend complaining about how hard it is to help Greg and Marcia with their respective extracurricular activities, Mike and Carol scoff at one another, saying the other has it easier with their kids' activities. As a result, Mike suggests they swap for a day to prove his point and Carol wholeheartedly agrees to the swap. However, it doesn't take them long to realize how difficult it can be helping their kids out with their activities – only both are reluctant to admit it to each other.
