Much Ado About Mousing
Tom’s fishing, but his bait is cheese, and his quarry an unusually gullible Jerry on a boat across the harbor. Jerry gets reeled in, but that’s only the start, particularly once Jerry hides in Spike’s mouth and gets Tom to pull Spike’s tongue out. Tom hauls a passing dogcatcher in, and he fetches Spike, but Jerry saws off the net, so Spike gives him a dog whistle. A set of earmuffs does the trick as Spike naps, but Jerry shows Tom the earmuffs, so Tom dutifully punishes himself as Jerry carries the duplicate earmuffs over to Spike and settles in for his own nap.
A Chuck Jones entry with the summonable-dog premise revisited: Jerry rescues a bulldog and is given a whistle to call him with. Jones stages the whistle gags with much longer pauses than Hanna and Barbera would have allowed, which either improves them or ruins them depending on who you ask.
