Eddie and Joy's free-spirited daughter, Ally, returns from a trek in the Ecuadorian rain forest with her new husband, Doug. When Ally and Doug decide to set up camp in a trailer in the Starks' backyard, they ultimately ruin Eddie's plans for installing a Jacuzzi. Meanwhile, Eddie and Joy attempt to overcome their dislike of Doug and accept him as a member of the family.

Eddie feels self-conscious when Tommy (guest star Gottfried) and Mr. White (guest star Mull) boast about their endowments, so Joy does her best to convince him that being average is just fine. Meanwhile, Doug and Ally have their first sonogram, and it appears that their unborn son doesn't take after Eddie.

When Whitey decides to throw a surprise party for his 93-year-old grumpy uncle, his party guests are surprised to discover that Whitey is a hoarder and his house is overflowing with junk. Meanwhile, Eddie is in a rush to get to the party but Joy, Doug and Ally all take their time getting ready to go.
