My Favorite Martian S3 E12 Avenue C Mob

Martin temporarily ages himself four hundred Martian years. He has been studying human old age, and figures one can only fully understand it by experiencing it. The one benefit however is that his mind is still as sharp as a tack, since Martian brains don't deteriorate with age. Martin decides that one of his acts as a senior on earth is to take a job as a warehouse night watchman since seniors don't want to be burden to their families. At work, Martin is interrupted by a couple of intruders, two elder spinster sisters, Tessie and Matilda Harvey. Their story: their estate, the possessions of which stored in the warehouse, is managed by Mr. Filbert.
