Ricki Lake reminds viewers to have their pets spayed or neutered à la Bob Barker. 'N Sync's Lance Bass plays Let's Make a Deal while dressed in a banana costume. These are just two of the small joys derived from CBS' kitschy Gameshow Marathon, a competition that pits six celebrities (including Leslie Nielsen, Tim Meadows, and Kathy Najimy) against each other in re-creations of classic game shows. The series is certainly goofy, but never fully reaches its fun potential. In other words, there are big bucks (and yuks) but also some Whammies.
