My favourite piece of information is that Branwell Brontë, brother of Emily and Charlotte, died standing up leaning against a mantle piece, in order to prove it could be done.

An editorial interpretation.
Adams calls this his favourite piece of information: a man who supposedly died standing up against a mantelpiece, just to prove it could be done. The delight is in the sheer pointless stubbornness, a fact prized for being absurd rather than useful.
