Explain My Mystery

Explain My Mystery was a game show on which the Second Doctor once appeared. Hosted by Perry Conway, the program challenged its panelists to explain real-life mysteries recounted by ordinary citizens.

Trapped on Earth by the Time Lords prior to his regeneration into the Third Doctor, the Doctor's second persona lived in luxury at the Carlton Grange Hotel and became a newspaper-headlining celebrity. {TVC: "Action in Exile", "The Brotherhood") He was therefore a natural candidate for inclusion on the panel of Explain My Mystery.  On the night he participated, he explained Mrs. Swiggings' mysterious "bumps in the night" with great ease, but ran into difficulty with Mr. Glenlock-Hogan's tale of "walking scarecrows".  Undeterred by being stumped on national television, the Doctor left the studio with Glenlock-Hogan to investigate the farm on which these scarecrows appeared.  There, they revealed that they had created the mystery in order to lure the Doctor to them.  Animated by the Time Lords, these scarecrows then captured the Second Doctor and forced him to regenerate.

Consequently, it could be rightly said that the Explain My Mystery studio was the last place where the Second Doctor was seen in public. (TVC: "The Night Walkers")
