Swingers concludes with one extra moment - Trent convinced he's about to score with a beautiful baby giving him "a vibe."
The punchline is, of course, that there's an actual infant in the booth, and Trent is just a putz. Plus, Mike's got a date lined up with the beautiful baby he met in the bar. He's absolutely over his ex from New York, just like Ron Livingston said he'd be, and everyone loves listening to Tony Bennett.
Perfect ending. Perfect film.
