Critics

 * The TV Critic: "I also liked the story being structured to reward Leonard for being agreeable and pleasant. He was rewarded for his social exploits with a big round of applause from his colleagues whereas Sheldon's cold indifference got him banned from future fundraising...Penny laughs at him for it which kind of missed the opportunity to shine a light on their feelings for one another but it was nice just to get an actual ending to a plot for once...This was a good story and the conclusion was passable. Lots of room for improvement but isn't there always?"
