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
