Road Rules - Season 11 Episode 9 Dean Jumping

The gang rolls into Texas for the Dean's List Bungee. They have to find pairs of people to jump with them that have something in common (like a librarian and a student with overdue library books...get it? Good!). It proves more difficult than it seems as they have trouble finding a physics professor to jump with Sarah. Which is probably the worst thing to happen as Sarah is gung ho about this mission. She wants to go ""balls to the wall"" on her bungee. Eventually she finds a physics prof to join in and give us an excellent explanation of gravitational force and kinetic energy that might have been about bungee jumping or might have been his recipe for meatloaf. Does anybody know anything about Physics? So the team completes the mission and wins more prize money but they are informed that they can win some trip money if they complete a mini-mission. Unable to find a dean to jump with them, they go with an athletics coach to get the lesser cash award.
