Told in flashback by a professor in an interview with a newspaper reporter, this is the story of The Stooges as traveling salesmen trying their best to sell their "Miracle Reducing Machine", which essentially shakes and rattles off the pounds (as Curly's demonstrates). As luck would have it, the boys stumble on the home of Graves the inventor (Ted Lorch), who assumes the Stooges are the new caretakers. Graves is on his way to Washington, D.C. to test his new death ray machine, and leaves his eerie spooky mansion in the hands of the trio. Naturally, spies disguised in Halloween costumes show up once Graves departs. The Stooges are on edge the entire time, particularly because mysterious cream pies come flying out of thin air. Back in the office the reporter is desperate to know who is throwing those pies. The professor confess that he was throwing the pies when out of nowhere a pie flew into his face.
