Caroline in the City - Season 4 Episode 11 Caroline and the Fright Before Christmas
Overview: Richard, Del and Annie are apparently successful in their combined effort to knock the Christmas spirit out of Caroline, but when she appears to have lost all interest in her annual tree-trimming festivities, her alarmed buddies declare an emergency trip to nearby ""Christmasville,"" only to discover that Caroline engineered the whole thing. When even the local re-enactment of A Christmas Carol doesn't do the trick, a furious Caroline tries to drive away and backs into the town's main transformer, blacking out all of ""Christmasville"" and condemning them to slave off their sentence in Santa's workshop.
