Look Who's Not Talking - S1.E7

Kim invites Christine along to a ""Mommy and Me"" group. The activities are so tiring for Christine that she tells Kim she won't attend them again. Kim responds by suggesting Christine could be a good parent if she'd do more with her kids. Christine retaliates by calling Kim a control freak, and soon the two aren't speaking. Their childish fight has repercussions for Greg and Jimmy when their wives won't let them talk to each other either. Jimmy plots to smooth things over between the dueling sisters by calling up both of them and telling them the other was in a car accident. When Christine and Kim each find out that there was no accident, they put aside their differences... and stop speaking to their husbands.
