5 second plot: Howard and Sheldon decide it's time to stop making fun of each other and become better friends. Penny's car breaks down. And she can't afford to buy a new one so she will have to go back to waitressing instead of focusing on her career as an actress. And Raj asks Amy to help him with online dating.
5 second review: Not very much new going on. Which is fine by me. It's still a lot of fun.
