The Jetsons

Private Jetson is drafted, as George is a family man he gets a full two minutes to report for duty. They're all given an aptitude test, and one not-so-bright recruit jams a square peg into a round hole, whereupon the automated grading program determines that his 'original thinking shows leadership potential' and makes him a general. Spacely turns out to be the commanding officer and the site is a full 10 minutes away.
