The Big Bang Theory: When Stuart, the sales clerk at the comic book store, charms Penny completely and gets her to go out with him, everyone is baffled at how he did it. Leonard’s dismay that Penny would go out with Stuart and not him drives him insane, but when an argument between Sheldon and Stuart results in a break-up between Stuart and Penny, Leonard offers his shoulder for Penny “to cry on”. Meanwhile, Howard and Koothrappali head to a women’s bar to pick up girls, and while Howard fails at getting sex, Koothrappali scores… surprisingly.
