The Big Bang Theory Episode 7.03 The Scavenger Vortex

The gang decides to plan an epic scavenger hunt in the vein of the old college scavenger hunts at Princeton and M.I.T. Koothrappali acts as the game master and plans the event, while the rest of the group pairs off into teams: Amy with Wolowitz, Leonard with Bernadette, and Penny with Sheldon. As they go through the various challenges, Wolowitz and Amy bond over their mutual love of Neil Diamond, Penny and Sheldon work surprisingly well as a team, and Bernadette reveals her insanely competitive nature.
