A Damsel in Distress by P. G. Wodehouse

Lord Belpher's twenty-first birthday dawned brightly, heralded in by much twittering of sparrows in the ivy outside his bedroom. These Percy did not hear, for he was sound asleep and had had a late night. The first sound that was able to penetrate his heavy slumber and rouse him to a realization that his birthday had arrived was the piercing cry of Reggie Byng on his way to the bathroom across the corridor. It was Reggie's disturbing custom to urge himself on to a cold bath with encouraging yells; and the noise of this performance, followed by violent splashing and a series of sharp howls as the sponge played upon the Byng spine, made sleep an impossibility within a radius of many yards. Percy sat up in bed, and cursed Reggie silently. He discovered that he had a headache.

Presently the door flew open, and the vocalist entered in person, clad in a pink bathrobe and very tousled and rosy from the tub.
