Roland: What are you doing?
Niles: I, uh...
Frasier: Uh, I can tell from the panic in my brother's voice that he must have seen a spider. You see, he has a crippling fear of spiders, and it sent him up the ladder.
Niles: Yes, I hate spiders.
Sarah: I don't see a spider. Come back down.
Frasier: No!
Roland: Why not?
Frasier: Because he also has a crippling fear of heights. And this may be just the breakthrough we've been looking for. Higher, Niles! Conquer your fear! Please, everyone, I'm going to have to ask you to turn around, as his fear of crowds has set in.
Sarah: Crowds, too?
Frasier: Yes, you are looking at that rarest of beasts, the arachno-acro-agoraphobe. Please, avert your eyes.
