July 15 to 19 The Montreal-based comedy spectacular Just For Laughs heads west for a giggle-inducing string of stand up shows. Monty Python’s John Cleese and Emmy Award–winning actress Sarah Silverman provoke jaw-dropping guffaws when they host separate galas on July 17 and 18 respectively, while Toronto’s favourite ad-libber Colin Mochrie (Whose Line is it Anyway?) guarantees laughs in an improv show with former co-star Brad Sherwood from July 16 to 18. Other stellar comics on the bill include Canadian funnyman Jeremy Hotz and Scottish sensation Danny Bhoy. Various venues, $22 to $120; call 416-872-4255 or visit Ticketmaster to charge.
