Julia's nineteen-year-old son, Payne, is bringing his girlfriend home from college for a visit, and Julia wants everything to be perfect for her ""baby."" Payne then presents his girl, Primmie, who is tall, attractive...and forty years old!

Charlene and Anthony scheme to outsmart Mary Jo's disbelieving son on Christmas Eve -- until their hired Santa beats them to it, by swiping the Sugarbakers' Christmas gifts.

Julia is not pleased to learn that Payne is graduating early in order to marry his pregnant girlfriend. Upset at becoming a grandmother so soon, Julia gets tipsy at the wedding, then wakes up mortified -- and scantily clad -- the next day with Payne's frat house roommate (Young).

Julia delights in the opportunity to dote on son Payne when he returns for a visit -- which Julia learns will be permanent.
