It’s comic-book-night for the guys, but they are surprised to see Leonard there. Howard and Raj were expecting him to be having sex with Penny, but as Leonard reveals only to get them off his back, the previous night they spent together was “just fine”. When Sheldon brings this up during a normal conversation, it shocks Penny what Leonard actually tells the guys. Meanwhile, when Howard and Sheldon hear a cricket in the apartment, they start arguing about what species the cricket belongs to, and end up betting their best comic books against each other.
