A Bunny for Tabitha

S6, E8: It's Tabitha's birthday and Uncle Arthur shows up for her party. Larry calls Darrin with the news that A. J. Sylvester is at the office and Darrin is badly needed to present a layout, but Darrin refuses to leave the party. Uncle Arthur puts on a magic show but his bunny trick is ruined when a Playboy-type bunny appears and won't disappear. Larry and Mr. Sylvester have come to the party and Sylvester is obviously impressed with the trick.
