Pantophobia

Lucy Van Pelt: Are you afraid of responsibility? If you are, then you have hypengyophobia.

Charlie Brown: I don't think that's quite it.

Lucy Van Pelt: How about cats? If you're afraid of cats, you have ailurophasia.

Charlie Brown: Well, sort of, but I'm not sure.

Lucy Van Pelt: Are you afraid of staircases? If you are, then you have climacaphobia. Maybe you have thalassophobia. This is fear of the ocean, or gephyrobia, which is the fear of crossing bridges. Or maybe you have pantophobia. Do you think you have pantophobia?

Charlie Brown: What's pantophobia?

Lucy Van Pelt: The fear of everything.

Charlie Brown: THAT'S IT!
