Here Comes the Groom (2x17)

:

When a rebellious and misguidedly romantic Molly tries to elope with Mcloskey, she is dragged home by the kids. There Nick, encouraged by the widow McPhee, subjects the runaway lovers to a series of courtship rituals, which dampen everyone's ardor; the harassed bride bolts from the altar. But since the reception's all paid for, Nick insists they hold it anyway.
