Now You See It, Now You Don't

Сезон 1, серия 19: In his efforts to help museum curator Wilbur Canfield (Cecil Kellaway), and incidentally, to expand the cultural horizons of his friend Tim (Bill Bixby), Uncle Martin (Ray Walston) "borrows" a controversial piece of Egyptian art to verify its authencity. Unfortunately, Wilbur loses his job as a result...and worse, security has been beefed up at the museum, making it harder for Martin to return the artifact than it was to remove it in the first place.
