The Stanley Milgrim experiment is a series of radical experiments that test the willingness of individuals to obey authority. Individual variables are changed in order to determine what influences the test subjects. In nearly every case, the fundamental result is the same.

Kramer has forgotten where he parked his car in a multi-level parking garage of a shopping mall and the gang walk around for an eternity looking for the car. Jerry needs to urinate and Kramer encourages him to do so in a dark corner where no one can see him. While doing so, he is spotted by an officer, and held in the officer's booth. Later in the episode, George is caught doing the same thing.

The MythBusters test the myth that talking to plants makes them grow better. They set up several test groups of bush peas, and all are under the same conditions except the type of sound to which they are exposed.

George tells a story about how when his father bought a car, he went on a multi-state excursion to find the best deal.
