The Five Mrs. Buchanans

Spare the Rod, Spoil the Buchanan (1x8)

:

The rest of the Buchanan ladies weasel their way out of babysitting Vivian's destructive twins, Lyndon and P.J., while she goes to the salon, so it's up to vulnerable Bree to watch them. But Bree quickly finds herself being terrorized by the twins, so the sisters-in-law encourage Vivian to discipline them, which Vivian does... only to wind up in jail for child abuse.
