The Big Bang Theory Episode 3.02 The Jiminy Conjecture

Leonard admits to the guys that sex with Penny was not all it was cracked up to be. He tells them in confidence that it was just "fine." While hanging out later as a group, Sheldon spills the beans, and poor Penny feels awful. Leonard tries to make up with her and they talk about why it is so weird between them. They decide they need to have a drink and loosen up a little bit. In the mean time, Sheldon and Howard make a bet regarding the type of cricket they hear chirping in the building. Once they find the cricket in question, they take it to the university etymologist played by Louis Black. Howard wins the bet and takes possession of one of Sheldon’s prize comic books. Penny and Leonard get a little too loose, and both end up getting sick, leaving their new intimate relationship in an even weirder place.
