Angua's story about Mrs. Gammage at Biers. Mrs. Gammage is an old lady who has been drinking at the undead bar since before it was the undead bar, and never noticed the change. She was robbed once. The stolen goods were returned the next day and the thieves discovered to be mysteriously empty of blood.
Dorfl recollecting Carrot's honest kindness and fighting even harder against the king when he notices Carrot later on in the book is definitely a topper.
