Frasier: Niles, I need your help resisting Lilith.
Niles: All right, all right. Let me think, let me think. I think I have the answer. When you feel yourself yielding to her, summon an image so repellent you will be incapable of any sexual desire. Remember the summer we were at Uncle Henry's farm, we found that dead horse lying in the hot sun crawling with maggots?
Frasier: Yes. Yes, of course.
Niles: Hold onto that picture. You can ride that horse to safety.
Frasier: Thank you, Niles. I think that just might do the trick. When it comes to an ugly image, you can't beat a dead horse.
Niles: All right. Feel up to facing her again?
Frasier: Yes. Let her bat her eyes all she wants to, she can push her breasts up to Canada, I won't budge.
