David Roberts
From Tardis Wiki, the free Doctor Who reference
David R was a viewer of Ghostwatch.
He was watching the show while Suzy Monroe was filming for it. He wrote an SMS to the show, saying that people shouldn't trust the ghosts. He made a typo in his message, writing "gohsts" instead of "ghosts". (WC: Ghostwatch)
Behind the scenes
