Leon Errol can't go out for a night of poker with the boys. His living-room chair is co-opted by his mother-in-law's dog; and she's thrown away his pipe tobacco to use the humidor to hold her knitting wool. Finally, wide Dorothy Christy lets Leon go to the corner store to get a six-cent cigar. On the way, he encounters his own double, whom he hires to play him while he enjoys a night out with the boys.
They don't even bother to do split-screen effects in this short; they simply shoot Leon acting in one register, then cut away to Leon acting in another. It's fairly effective, and a good reminder that comic acting is acting.
Look at the old comedy pros in the poker game with Leon. We shall not look on their like again.
