S8·E15 Samantha's Magic Sitter

Esmerelda's magic seems to be all wrong and is a failure as a witch. Larry says that a client of his needs a babysitter for the evening and gets Esmerelda to do the job so he can sign the contracts to win the deal. Esmerelda shows the Norton's child, Ralph, some magic and No one believes him when he tells all about it. As a result, Esmerelda is fired and Larry loses the Norton account. So Samantha sets up a dinner party with Esmerelda as a magician. Once everything is cleared up, everyone gets what they wants: The Nortons are friends again and Larry wins the account.
