"Hizzoner the Penguin" was Burgess Meredith's first appearance this second season, and easily his best. A series of carefully conceived 'good deeds' have the effect the cagey bird requires, since he has decided to run for mayor and depose Mayor Linseed (Byron Keith, making the fourth of his ten appearances). Crack pollsters Gallus (George Furth), Rooper (Woodrow Parfrey), and Trendek (Murray Roman) predict easy victory for The Penguin, so Batman gets the call as Gotham City's last hope of victory. While Penguin entertains his followers with champagne and music (supplied by Paul Revere and the Raiders, who don't sing), Batman's sincere oratory seemingly puts his crowd to sleep! A request from the Grand Order of Occidental Nighthawks leads to a short Batfight, the Dynamic Duo suspended above a vat of sulfuric acid, getting lower as the ice continues to melt. Citizen Penguin arrives to put a stop to the horror, but unable to scrounge up a dime to phone the police decides to walk over to headquarters, only a matter of hours! Unbilled cameos include Western veteran sidekick Fuzzy Knight as the blind news dealer, and The Three Stooges' Joe Besser as a Penguin supporter.
