Sheldon, Raj, Leonard and Howard acquire a collectible casting of the One Ring, which turns out to be a prop from The Lord of the Rings film trilogy. The group is conflicted on what to do: Leonard wants to send it back to Peter Jackson, Raj wants to sell it and use the profits to buy a jet ski, and both Howard and Sheldon want to keep it for themselves. Leonard gives it to Penny for safekeeping, but Sheldon attempts to steal it while she sleeps and she punches him in the nose. The fight escalates at lunch at the university when all of the guys grab the ring and begin a holding contest, with the last one holding on the keeper of the ring. They somehow walk out the door of the university, get in a car and drive home. Leonard drops out when Penny tempts him with sex. The remaining three try several mind tricks on each other to give up the ring such as attacking their mothers or trying to make the other go pee, which works and Sheldon and Howard have to somehow urinate without letting go of the ring.
