After Tom raises a white flag, surrendering to Jerry & the two Indian mice, all four smoke a peace pipe, Jerry & the two mice "puff" the pipe correctly. When it is Tom' turn, the smoke apparently went down the wrong side of his esophagus. When Tom tries to puff & no smoke comes out of his mouth, he accidentally swallowed the smoke. Three seconds later, three puffs come out of his left ear & three come out of his right eat (at the very same time) apparently to spell out THE END.
