Near the opening of Hyprov: Improv Under Hypnosis, Colin Mochrie refers to himself as “international comic icon,” but if you haven’t ever seen What’s My Line, Anyway? you might be skeptical of his sweeping claim. (Mochrie’s wry delivery suggests that the description is a bit of a spoof.) Nevertheless, the Canadian native is definitely the funnier half of Hyprov, which combines two disciplines into something unusual and raucously entertaining.
