That Was No Chick, That Was My Wife - S4.E10

Darrin and Samantha are in Chicago to work on the Springer Pet Food account. Baby-sitter Aunt Clara panics when Tabitha brings one of her toys to life. Samantha pops home to check up just when Louise arrives at the Stephen's home. Major confusion ensues when Larry gets word that Samantha is at home, not in Chicago with Darrin. When Mr. Springer sees Sam & Tabitha outside McMann & Tate, he realizes that she was indeed the woman in Chicago with Darrin, and the problem is solved.......well, except Louise is sent to a psychiatrist. Samantha saves the day by introducing Louise to Serena.
