Is it wrong to continue seeing a woman you have nothing in common with - except great sex? That's the question Frasier asks himself when he falls into a purely physical affair with a free spirit named Caitlin. Knowing he should break it off, Frasier repeatedly tries to do so, only to wind up back in the sack with her.

Finally, Frasier decides it's only fair to call it quits with Caitlin because their steamy relationship can never really go anywhere. He goes to Caitlin's house, where he's shocked to learn she's chopped off all her hair, and stunned to hear her howling at the moon as part of her membership in a werewolf society.

Despite all the weirdness, Frasier still can't fight his chemical attraction to Caitlin and when she offers to give him a massage, he winds up spending one last night with her before they break up for good.
