In the original airing of this episode, there was a 1-900 number so viewer can choose who was the actual killer. Therefore, there were three different endings shot for this episode. The text of NBC's statement on the show is as follows:
A killer's fate is in your hands. Now, you decide who killed Robert Ullman. Call in now. If you think Jane Barnes killed Robert Ullman, call this number; if you think Don Ridgley killed Robert Ullman call this number and if you think Stephen Spector killed Robert Ullman call this number. Your vote will help decide how this episode should end. Jot down these numbers. The lines are open now. All calls received during the next seven minutes will be counted. You decide who killed Robert Ullman. There will be a 50 cent charge for each call. NBC's proceeds will be donated to charity and your call will be answered by recorded announcement. Children should ask their parents' permission to call. Call in and stay tuned to see who America believes killed Robert Ullman.
The DVD release contains a choice to play the episode as originally aired or to select an ending from the three choices.
