From ctv.ca:
"GAMESHOW MARATHON features six celebrity contestants competing in a weekly elimination-style tournament in which they play different classic game shows each episode including "The Price Is Right," "Let's Make a Deal," "Beat the Clock," "Press Your Luck," "Card Sharks," "Match Game" and "Family Feud." Celebrities participating include Tim Meadows ("Saturday Night Live"), Leslie Nielsen ("Airplane"), Kathy Najimy ("Sister Act"), Lance Bass ('N Sync), Paige Davis ("Trading Spaces") and Brande Roderick ("Baywatch").
A champion will be crowned at the end of the competition. In addition, the program will include a viewer participation element whereby they will have a chance to win the celebrity's grand prize each episode through a wireless (text message) trivia game that enters viewers into a sweepstakes."
There's also a neat banner of Rikki Lake and her mic in front of TPiR set.
