While rummaging through their closet, Leonard finds a DVD he rented using Sheldon's card, that should have been returned seven years before. Leonard desperately asks Sheldon not to flip out, and he shockingly remains calm and agrees. He makes Leonard wear an itchy sweater until the DVD issue is resolved, so that Leonard can, metaphorically, walk in Sheldon's shoes. Leonard searches for the DVD store (long out of business), then for the owner (deceased), then the owner's (nonexistent) next-of-kin, all the while getting a bad rash from the sweater. Sheldon eventually tells Leonard he had discovered the DVD and paid the fine years before, and that he just wanted him to learn the lesson, much to Amy's surprised and shocked look on her face. Penny meets Lucy, Raj's ex-girlfriend, at the Cheesecake Factory and is mad at her for breaking up with him by email. Lucy calls Raj to have coffee to apologize. Raj hopes they can get back together, but Lucy reveals she is now dating someone else. Penny then sets up Raj on a date with her friend Lizzy, but Raj freaks out in front of her.
