If you were a Canadian kid during the 1980s, you have recently lost a piece of your childhood as Irish-Canadian actor Gerard Parkes just passed away at the age of 80. Of course, Parkes is best known for playing the role of Doc on the iconic Jim Henson series, Fraggle Rock. Prior to Fraggle Rock, Parkes had been acting on Canadian television for years, so it’s probably inevitable that he once made a guest appearance on another Canuck institution, The Littlest Hobo, playing a doctor who is helped by the dog to track down a man with the plague.
