This wasn't one of Season 5's best. Leonard's high school bully from New Jersey is randomly visiting Pasadena, California to visit him. The scene at the bar was too long and I thought the list of things he did to him as teenagers was a little unrealistic. (the fact that he wrote a list) It was good to see Sheldon stand up for Leonard but to see spineless Leonard let a drunk Jimmy sleep on his couch was pathetic. A sober Jimmy returned to his obnoxious self the next morning, and Leonard made about as much of a "stand" as he's ever made, although I was hoping he'd of done something more epic like punch him in the face. If not that, I didn't like how Leonard and Sheldon running down the stairwell was the closing sequence to the A plot. The B plot, I just thought, was there to get 24 minutes of episode in. Again, Penny, Bernadette, and Amy together provided a boring storyline.
