My Man Jeeves (Jeeves, #1)

by P.G. Wodehouse

A portrait-painter, he called himself, but he hadn't painted any portraits. He was sitting on the side-lines with a blanket over his shoulders, waiting for a chance to get into the game. You see, the catch about portrait-painting—I've looked into the thing a bit—is that you can't start painting portraits till people come along and ask you to, and they won't come and ask you to until you've painted a lot first.
