Originally scheduled to start airing in January 1984, "The Duck Factory" sitcom debut in April, airing Thursdays at 9:30pm between "Cheers" and "Hill Street Blues". The same month, Carrey took a job hosting the 1984 U-Know Awards ceremony held in Toronto at the Royal York Hotel's Ballroom. By the time he made his debut appearance on NBC's "Late Night with David Letterman" in late July 1984, the network had already cancelled "The Duck Factory"; Carrey went back to touring with his impressionist act, including often opening for Rodney Dangerfield.
