The six-year on-again, off-again relationship between Robert (Brad Garrett) and Amy (Monica Horan) is definitely on again in this pivotal episode. So much so, in fact, that ""Robert wants to propose to Amy,"" says executive producer Philip Rosenthal. But there's one formality the hopeful groom-to-be must take care of first: asking Amy's devout churchgoing folks (Fred Willard, Georgia Engel) for their daughter's hand in marriage. To that end, ""Robert convinces Ray to accompany him to meet her parents in [Pennsylvania],"" says Rosenthal. How they---and possibly Amy---respond determines whether wedding bells will be ringing anytime soon. Peter: Chris Elliott. Frank: Peter Boyle.

Robert and Amy exchange vows in a classic Barone family wedding ceremony.
