Imagine the Audience Naked: Although it's "Imagine Them In Their Underwear," a tactic Jan uses to relieve her nerves and perform well during the debate. Jan who had gotten the bit of advice from Mike passes on the advice to Marcia, and it works! (Only the driver's examiner is seen in his underwear, which consists of a "wife beater" and boxer shorts.)
Performance Anxiety: The driver for much of the plot Marcia's first driving test, Jan's inability to perform in debate club ... and in the end, Greg losing the obstacle test.
Wager Slave: Greg and Marcia agree to a driver's obstacle course, with the loser having to do the winner's chores for a week.
Wiper Start and Had the Silly Thing in Reverse: Marcia actually starts the wipers - and raises and lowers the convertible top, to boot before beginning the first test. She also jerks the car backward the car doesn't hit the vehicle parked in back of it after becoming even more anxious.
Women Drivers: Greg tries to use this against Marcia, and ultimately fails.
