"Robert’s Wedding"
Like their relationship, Robert and Amy’s road to the altar is rocky. When Peter attempts to bury the hatchet between himself, Robert and Ray, Robert suspects he’s up to no good and assigns Ray to keep an eye on him. Meanwhile, Robert and Amy exchange vows in a wedding ceremony that has the Barone family tradition written all over it. Fred Willard, Georgia Engel, and Chris Elliott guest star as Amy's parents and brother.
