Ah, Fredegar Bolger. You remember him, don't you? No? He was one of the brave hobbit-heroes in The Lord of the Rings, one of Frodo's friends; he played an important role in the quest of the Ringbearer.
Almost nobody remembers Fatty Bolger, of course, because he never left the Shire. Fredegar's role in the plan was to stay in the Shire and pretend to be Frodo, so that no one would know that he had left, at least for a while, and also to let Gandalf know what was going on when he turned up. As the narrator darkly remarks (Book I, Chapter v), "They little thought how dangerous that thought might prove." Since Frodo and friends were actually just skirting doom by a hair, and Gandalf was a bit occupied elsewhere, Fredegar narrowly managed to escape three Ringwraiths (Book I, chapter xi).
This is not the last we hear of Fredegar, though. He is rescued by the returning questers after the Scouring of the Shire. When the Shire began to be overrun with ruffians, he did not stand idle: he led a band of rebels in the north until he was finally smoked out and thrown into the Lockholes in Michel Delving (Book VI, chapter ix). Not every hero leaves his home.
