Fri, 05/18/2012 - 18:35 — ncsurveygirlI didnt know they canceled it. This makes me so sad, I absolutely love this show! Isnt Lisa Kudrow involved in making this show, cant she just throw more $ at NBC. Or what about all the B list and lower celebrities who go on shows like the Apprentice and DWTS, I wish they would be fighting to get on this show for extra attention! At least Shark Tank got renewed!
