The Fuzzy Boots Corollary

Summary
While playing Age of Conan, the group attempt to retrieve the sword of Azeroth. Sheldon betrays them and sells the sword on Ebay which Howard buys (See Quotes below). Then later in the episode, Leonard sees Penny kissing a guy in front of her apartment door, he is devastated thinking she has 'rejected' him. The guys convince him to ask someone out at work, but when he tries and is brutally turned down by a geeky girl scientist named Leslie Winkle (Sara Gilbert), he is even more depressed. As Leonard slips deeper into his depression (which involves thinking about buying a cat and listening to emo music), Sheldon (in an attempt to not have a cat) points out that he was not actually rejected, as he had not asked Penny out. Leonard agrees and promptly asks Penny out to dinner, but she mistakes his invite as an invitation to hang with all the guys. Despite being aware of this, Leonard keeps the date and makes up excuses as to why the guys were absent.

On the date, Penny mentions the man Leonard saw was not her boyfriend, but that she has a habit of having weekend long flings to get over relationships. Excited, Leonard begins to become more confident but, after accidentally hurting himself, the date becomes a disaster and Penny takes him home. Leonard does not get the courage to reveal his true feelings to Penny, even though she suspected what he was up to.

Title reference: One of the names that Leonard was considering for his cat.
