The morning after Kate and Frasier succumb to their passion, they both have second thoughts about an office romance. But when they start reminiscing about their fling, Frasier admits he enjoyed feeling like a “bad boy” and Kate agrees she liked being a “dirty girl.” They sneak into a sound booth, but in the midst of their lovemaking, Frasier realizes their cries of ecstasy are being broadcast to all of Seattle!

Meanwhile, Martin is being pursued by Dierdre Sauvage, a neighbor who also happens to write steamy sex novels. Dierdre is moving out of the building, but continues to make unwanted advances toward Martin.

The next day, Frasier receives some good-natured ribbing from Roz and Bulldog, who want to know the identity of the “dirty girl.” Kate hears the joking, and suspends Frasier for a week. She later visits Frasier’s apartment to apologize, but reminds him that she had to keep up appearances. They vow to stop their romance, but when they become stuck in an elevator, they can’t help but fall into each other’s arms again.
