At Tabitha's birthday party, Uncle Arthur does a classic rabbit in a hat trick, but instead of pulling out a rabbit, he pulls out a Playboy bunny! Darrin's new client, A.J. Sylvester, comes to the party with Larry and instantly falls for rabbit-turned-human (who's given the name Bunny). When A.J. and Bunny have lunch together, A.J.'s ex-girlfriend comes up, sees him and leaves in anger. Samantha invites A.J. and Bunny to dinner and A.J. announces that they are to be engaged. But that doesn't last long when Bunny's rabbit qualities finally come to light.
