Kim drives Greg up the wall when she worries that Sam isn't walking yet. Jimmy advises Greg that he should let Kim have the day off if he wants her to lighten up. So Greg arranges for Kim and Christine to go a day spa, giving him and Jimmy a day alone with the kids at the park. Jimmy gets hot at the park, and talks Greg into taking the kids someplace else that's cool -- a casino. Greg catches Sam on tape taking his first steps in the casino lobby, but then realizes that he can't show the video to Kim because of where it was taken. While waiting for their massages, Christine manages to talk Kim into relaxing more when she returns home. Jimmy pays a friend to digitally alter the background in the tape to a park, so Greg can show it to Kim. Kim is thrilled to watch it, until she -- and everyone else -- views Sam walking right over a pond! Greg has no choice but to come clean with Kim about what happened, causing her to unravel all over again.
