Yes, Dear - Season 3 Episode 10

When Kim and Greg decide to go on TLC's A Baby Story, they run into major problems with their parents. For example, when Kim and Greg announce that they want to name the baby Charlie if it's a boy and Lucy if it's a girl, everyone calls out with their own picks for a girl. Kim's dad wants the baby to be named Rachel, and Greg's mom wants the baby to be named Margaret if it's a girl. The baby indeed turns out to be a girl, and as Kim and Greg are about to pick the baby up from the nursery, they hear Greg's dad stating that he wished that his own daughter were named Emily after his aunt who practically raised him. After overhearing this, Kim and Greg decide to name the baby Emily.
