Just for Laughs and Just for Laughs: Gags are Canadian shows. I don't know if they're shown outside of Canada. But anyway, Gags is so hilarious. People play pranks on the public, mostly out on the street. Some are just simple pranks like fake police officers trying to issue tickets for no apparent reason.
I remember watching a really funny one yesterday where a lady (part of the crew) was put into a freezer and with makeup, it looked as though she was stuck in there for a while. So anyway, it was filled with ice and put outside a store. So when the public would open the freezer the lady would stare back and, after a few seconds, shiver madly. Most people ran away or screamed. I couldn't stop laughing after seeing everyone's faces from the hidden cameras.
