Jethro gets a letter from the President to enlist in the Army. Jed doesn't want the Government to pay for Jethro's training so he wants to pay all the expenses. Mr Drysdale isn't happy when Jed wants to withdraw $100,000 to buy Jethro a tank. He's even less happy when Jethro wants Mr Drysdale to be his tank crew dressed as a German Officer. Jethro drives the tank to Griffith Park for target practice, Mr Drysdale escapes in a rowboat & rows to the middle of the lake. Jethro is about to fire at him when two cops arrive & Mr Drysdale thinks he's saved. Until the older cop recognises him from his days in the quartermaster corp & arrests him as payback. Jed has to bail out Mr Drysdale.
