Mint Men

Undercover treasury agents Heckle and Jeckle are assigned to test a new security system at the United States Mint. The mint has two defenses: dumb guard dog Dimwit and a money-sniffing robot. The super crime-fighting robot is programmed to capture and destroy any and all thieves in the U.S. Treasury, and then return any stolen money to the mint. The duo manages to steal the money from the mint and return it to the vaults of the mint. When the going gets tough, Heckle and Jeckle toss the money to the guard dog. The robot seeks out the money and clobbers Dimwit, the chief security guard. Their assignment complete, Heckle and Jeckle are hailed as heroes. But Dimwit gets the last laugh when he sends the super crime-fighting robot after the hapless pair and sends them running into the streets.
