Jeffrey David Newfield (12 May 1952 – 18 December 2016), known as Scruff Connors, was a Toronto-born Canadian radio broadcaster known for conducting controversial on-air practical jokes. His career included host duties at various radio stations in Canada and the United States. His most prominent work was with Q107 in Toronto, where he became morning host in 1980. After broadcasting in other cities, he returned to Q107 in the early 1990s to join "The Q Morning Zoo". In 1980, after Terry Fox was forced to abandon his Marathon of Hope, Connors responded by raising CAD$72,000 for cancer research by continuously hosting a 36-hour "Scruff-a-thon" on Q107.
