Yes, Dear

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.

Greg and Kim are hardly enamored with Jimmy's and Christine's method of potty training Logan -- stripping him naked and letting him run around in the Warners' backyard until he figures it out himself. But since Sam is the same age as Logan, Greg thinks it's time to start potty training Sam as well. Just, uh, not by using the Hughes method. Greg and Kim take Sam out to buy big kid's underwear and a bunch of potty training aids the parenting books recommend. Jimmy and Christine think all the aids -- among them, a doll called Potty Scotty that poops ping pong balls and a child's first potty training video -- are ridiculous, especially since they're not working. Kim then tries to use Greg's bodily functions as Sam's training video, without consulting Greg. After Logan trains himself before Sam does, Greg begins to wonder if they should try Jimmy's and Christine's way, but Kim thinks they should just give up and try again later when Sam's ready. Greg, however, decides to take potty matters

When Christine catches Dominic in his fifth lie in one week, she goes to Jimmy, who decides that he has to put his foot down with the kid -- despite the fact that he's been the softie parent all along. But when Jimmy's tough talk doesn't stop Dominic from lying, he plans to give Dominic his first spanking, against Kim's advice. Christine sides with Kim at first, but then she remembers how spanking worked on her, and agrees to let Jimmy go ahead with it. Since it hurt Jimmy more than it did Dominic, Jimmy makes it up to him by offering to take him to the go-cart track. But right before their trip, Jimmy finds out from Christine that Dominic lied yet again. Although neither Jimmy nor Christine can muster up the strength to administer more corporal punishment on Dominic, they inadvertently stumble onto the answer: Jimmy tells him he's not taking him to the go-carts... thus showing him how it feels when you lie to someone.

Greg plays tough uncle when Jimmy and Christine aren't as strict with Dominic and Logan as he would like.

Competitiveness gets the better of Greg and Kim and Jimmy and Christine after Sam's new girlfriend ""dumps"" him for Logan.

The surprise firing of Mr. Savitsky leads Greg to find him working in a soup kitchen.
