Desperate to make a love connection, bachelor brothers Frasier and Niles throw a big singles party at Niles' apartment. Martin gets into the spirit of things by dying his gray hair brown in the hopes of looking younger, and a very pregnant Roz attends the bash to see if she can still remember how to flirt.

The evening starts out swimmingly, with both Frasier and Niles excitedly telling each other that they've met the perfect match. Too bad they're both interested in the same woman! While they compete for Vicky's affections, Martin is aghast to learn that sitting by the hot fireplace is causing his hair dye to "run."

Just when things couldn't get any worse, Roz announces that her water has broken and asks Frasier to drive her to the hospital. Martin, Daphne and Niles join Frasier in the waiting room, and at long last, are greeted with the news that Roz has delivered a healthy baby.
