Every July, Montreal hosts one of the largest comedy festivals in the world, the Just For Laughs Festival. Founded in 1983 as a small French-language show (Juste pour rire) comprised of only two nights, in 1985, the organizers opened the stage to English-speaking comedians, paving the way for newcomers like Tonight Show host Jay Leno and sitcom star Jerry Seinfeld to launch their careers. In subsequent years, the organizers extended the festival—today there are more than 1,300 shows and performances, featuring all kinds of comedy as well as juggling and performance art.
