The Three Amigos (Episode 6862)

When Tyrone Dobbs took Molly Compton to the expensive La La Lounge restaurant with the intention of proposing to her, suddenly the restaurant lights dimmed and The Three Amigos started playing a medley of songs for a couple that were dining at a table nearby who'd just got engaged. With Tyrone's plan completely overshadowed, he swiftly ushered the waiter away who was by this time heading towards their table with his grand gesture for Molly - a bottle of cava and a sparkler.
