If a prank has been filmed in Canada in the last five years, Toronto-based special-effects guru Brendan Callaghan has probably been behind it. This would include creating life-like monsters and aliens to designing pranks for Howie Mandel. A former bartender with a knack for blowing stuff up, Brendan lucked into a TV
art department gig in 1996, but stepped in front of the camera for the first time as the co-host of Prank Science.
