Ken Kesey. Over the cuckoo's nest (№ 54074)

He got no hair on his face and none on his head to speak of; it looks like he glued some on once but it kept slipping off and getting in his cuffs and his shirt pocket and down his collar. Maybe that's why he keeps his collar so tight, to keep the little pieces of hair from falling down in there. Maybe that's why he laughs so much, because he isn't able to keep all the pieces out.
A person without hair, and their heads so much that even considered not worth it; it seems that he once stuck, and they do not hold and fall, some in cuffs, some scruff, some in a shirt pocket. Therefore, probably, and his collar so tight, to less hair filled. Because it can, and laughing all the time that the neck is tickled.
