Let's Make a Deal is a television game show which originated in the United States and has since been produced in many countries throughout the world. The show is based around deals offered to members of the audience by the host. The traders usually have to weigh the possibility of an offer being for a valuable prize, or an undesirable item, referred to as a "Zonk". Let's Make a Deal is also known for the various unusual and crazy costumes worn by audience members, who dressed up that way in order to increase their chances of being selected as a trader. The show was hosted for many years by Monty Hall, who co-created and co-produced the show with Stefan Hatos. The current version is hosted by Wayne Brady, with Jonathan Mangum (announcer), Tiffany Coyne (model), and Cat Gray (live musician) assisting.
