Montreal’s annual comedy festival Just For Laughs/Juste pour rire. It is the largest and most important comedy festivals in North America. Many American TV producers come to the festival to watch new comics and find new TV stars. There are many English and French comedy shows. Many of the comedy shows are on TV later. There are free street performances every afternoon and evening at Place des Festivals (Metro Place-des-Arts).
One of the favourites is the free Twin Parade, with dozens of twins walking in a parade.
