Rex Reilly
From Wikipedia, the free encyclopedia
Rex Reilly is a fictional host of the Jerry Springer-like TV talk show, The Rex Reilly Show, within the Canadian sitcom, Twitch City.
Bruce McCulloch played Reilly in the first season and Mark McKinney played him in the second. The change in Reilly's appearance is explained in his autobiography, Tyrannosaurus Rex, which refers to his "on-air cranium transplant."
Joyce DeWitt plays herself as a guest on The Rex Reilly Show, meeting lookalikes in an episode of Twitch City devoted to the theme "I Look Like Joyce DeWitt". Reilly, at one point, asks DeWitt about the enduring popularity of Three's Company, to which she responds, "It's the writing."
