Sir Herbert Wellingford

 is a warlock who has been trapped in a painting in the Tower of London for four-hundred years.

He fell in love with a witch in the court of King Henry VIII and asked her to marry him. His wife Malvina found out and trapped him in a painting, a curse to last for one-thousand years.

Four centuries later in 1971, Samantha and Darrin are touring the tower on their European vacation. Sir Herbert gets Samantha's attention and she stays behind after the tour group moves on. He says that he is not sure if her powers can release him, but he begs her to try. She agrees and zaps him out of the painting. He kisses her hand and says that he is her slave and will do anything for her.

Malvina appears and demands to know who gave Samantha the right to reverse her curse. Samantha says that nobody did, and apologizes. Malvina does not accept the apology and demands that Samantha put her husband back into the painting and Samantha complies. Then Malvina punishes Samantha, sending her back to the court of King Henry VIII without her memory.
