Pongo Twistleton

Reginald "Pongo" Twistleton is a character in the Uncle Fred books by P. G. Wodehouse. He's a nervous young man described by the woman who loves him as a "baa-lamb". Due to his craven disposition, he's easily bullied (in a good-natured way) by his Uncle Fred, who gets him to go on mad adventures where they impersonate people (see the Uncle Fred entry for some details). However, at the end of Uncle Dynamite, he is persuaded to push a policeman into a pond for a good cause.
