 During the filming of the final season, NBC refused to let the producers know  whether or not they had been renewed until after the filming of the final  episode, in order to try and draw in viewers. To compensate, the creators  filmed two different endings. In the first ending, which was shown on network  television, the Solomons went back to their homeworld and erased Marys  memory. In late 2001, the second ending was shown in syndication for what was  billed as the "first and only time." This "second ending" is actually an  extension of the original: Mary wakes up and goes to the Solomons car and  finds that Dick has given her the keys (you can see Dick tucking something in  her hand in the original broadcast ending). When she puts the key into the  ignition, a naked Dick appears next to her in the car and screams "ALIEN  ABDUCTION! ALIEN ABDUCTION!" before grabbing Mary and disappearing with her.
