When Annie and her newly engaged dads learn that their awesome cousin "Scooby" can only attend one of their weddings, they are drawn into a subversive "bride war" over whose wedding will win out. Meanwhile, after he is stood up by Dennah and Kay, Gil bonds with a group of sixth grade boys over basketball and laser tag.

The gang makes preparations to attend a baby shower but nobody can remember the first name of the host and they have developed elaborate ways to hide this fact. Meanwhile, Annie and Jake are considering their own family planning and their impending appointment with their fertility specialist "Dr. What's-His-Name" has put Jake a little on edge.
