Yes, Dear (2000)

S1E7 Look Who's Not Talking

Kim brings Christine to a "Mommy and Me" gathering, but the exhausting activities lead Christine to declare she won't be attending again. In response, Kim suggests that Christine could improve as a parent by being more involved with her children. Hurt, Christine labels Kim a control freak, resulting in a complete communication breakdown between the two. Their petty dispute starts affecting Greg and Jimmy, who are also banned from talking. To mend the rift, Jimmy concocts a scheme, falsely informing both women that the other has been in an accident. When they discover the truth, they reconcile... but choose to ignore their husbands instead.
