This week, Sheldon lends money to Penny in order to help her out with bills, but this leads to a confrontation between Leonard and Penny's ex-boyfriend, Kurt.
The episode began with the guys looking at their magic erase board, only to find that it wasn't a theorem they were discussing, but rather a strategy to find the most logical path to go to a restaurant, grab an icy, and still make it to the movie theater in time. Eventually they decide there was "no Sheldon approved movie theater near a Sheldon approved Restaurant," so this leads them to come up with the only solution: leave without Sheldon. And they did exactly that.
The next scene shows Sheldon about to enter his apartment (while the others were out enjoying a movie), when all of a sudden Penny frantically runs up the steps. "Shut the door, shut the door!" She eventually runs into his apartment and then Sheldon, following her directions, shuts the door, leaving him outside in the hallway and her inside the apartment (LOL). Penny then opens the door, drags Sheldon in the apartment, and puts her ear closely to the door. Sheldon soon imitates what she is doing and states, "I don't understand what social situation this is." Penny finally tells Sheldon that she is low on rent and without any hesitation Sheldon gives her money to borrow. (The money was conveniently placed inside a fake can of peanuts with a couple fake snakes inside the can "guarding it.") One of my favorite scenes is when a very hesitant Penny takes the money from Sheldon. Like a kid in a candy store she continued to take a bill, then give it back, then take a little more.
The next few scenes show that lending money was an easy thing for Sheldon, but Penny is not taking it so easily (or calmly). During a run-in with Sheldon and Leonard by the mailboxes, she freaks out when a package came, quickly explaining to him that this was a purchase from months before. In another scene while the gang is eating Chinese food, Penny thinks Sheldon was interrogating her because she ordered Chinese food and storms out of the apartment.
