“See, phrenology is this old Victorian science, which claimed you could determine the dominant traits of a man's personality by studying the bumps on his head. The size and position of these bumps indicated different personality traits. See? Now, /retro-phrenology/ says, why not change a man's personality by hitting him on the head with a hammer, till you raise just the right bumps in the right places!""One of us needs a lot more drinks," said Alex. "That's starting to make sense.”

“it was a delusive pie, the crust being like a disappointing head, phrenologically speaking: full of lumps and bumps, with nothing particular underneath.”

“You´re sure nothing happened when you bumped your head?" she says at last. "Like...personality transplant?”

“When you see a small change in your life it means its a huge change in personality and your trait”

“Here is Edward Bear, coming downstairs now, bump, bump, bump, on the back of his head, behind Christopher Robin. It is, as far as he knows, the only way of coming downstairs, but sometimes he feels that there really is another way, if only he could stop bumping for a moment and think of it. And then he feels that perhaps there isn't.”

“In general, lives seem to veer abruptly from one thing to another, to jostle and bump, to squirm. A person heads in one direction, turns sharply in mid-course, stalls, drifts, starts up again. Nothing is ever known, and inevitably we come to a place quite different from the one we set out for.”
