Pretty Boy Percy, "the world's greatest jewel robber," gets a face-lift to look like Mack, one of the janitors at Norman's Jewelry Store. He knocks out Mack, then joins Myer on the clean-up crew. But Mack regains consciousness, and Pretty Boy has to keep conking him on the head while stuffing jewelry into a bag. Myer notices "Mack" speaks in a deeper-than-usual voice, and offers him an aspirin and a glass of water, assuming "Mack" is sick. "Mack" rejects the offer, but the real Mack has a headache and asks for an aspirin. This routine goes back-and-forth a few times until "Mack" pulls a pistol on Myer, who throws water in his face and escapes. The police barge in and make an arrest...but did they get the right guy?
