Uncle Albert

 is Darrin Stephens' uncle.

Uncle Albert is a construction engineer. Because he is on the road all the time, he had no time to marry or have a family. He is a little eccentric and likes to pull gags such as pulling a mouse out of his pocket. Darrin says he is not very good at the gags, however.

Uncle Albert stops by the house for an expected visit, but Samantha is busy upstairs with Tabatha. Horace Dilliway, a bum posing as Uncle Albert, answers the door and tells him that the Stephenses moved away two weeks ago. Uncle Albert leaves, wondering why Darrin never said anything.
