Genevieve

“Well … here it is, Princess. I once knew a girl called Genevieve who suffered from arachibutyrophobia.”
“You’ll just have to tell me, Willie.”
“It means an obsessive fear of peanut butter sticking to the roof of your mouth. I thought everybody knew that.”
“Tell me, Willie,” she said, “how did you cure her?”
“Well, when she’d spread the peanut butter on the bread, I got ’er to bite into it upside down. Made ’er very ’appy. Fat, but ’appy.”
(Dead Man’s Handle, chapter 10)
