Just Good Friends - Season 3 Episode 7 The Wedding
Overview: Penny and Vince are planning to get married again but are being held to ransom by Gina. Not only has she 'arranged' for Penny to go back to work in Paris but is refusing to employ Norman or import Les's wines unless they call off the wedding. So the couple are forced to announce the postponement of the ceremony. However they are not around to attend the party to celebrate Gina's change of heart and ensuing security for their parents - chiefly because they are both in Paris, tying the knot in secret.
