To chase after a woman with whom he had no chance - again - Howard leaves Raj at a critical moment during a kite flying challenge against Sheldon and Leonard. This is the last straw for Raj who sees himself as second priority behind Howard's quest for unattainable women. Will Howard be able to regain Raj's friendship? Meanwhile, Leonard learns that Penny has not invited him to a football game watching party at her apartment. He realizes that he has never met any of Penny's friends, which makes him think she's ashamed of him. She assures him that it is only because she feels he will be bored. But to fit in with Penny's friends, Leonard makes an effort to learn all about football by watching games and reading text books on the subject. Not quite grasping the whole football game watching culture, Leonard soon learns that someone unexpected in his own social circle knows all about football and may be able to teach him better than "Football for Dummies" can.

Did You Know?


Sheldon (Jim Parsons) instructs Penny (Kaley Cuoco), "You shouldn't keep your bread in the refrigerator. Staleness is caused by crystallisation of the starch molecules, which occurs faster at cool temperatures." In episode 1.4, The Big Bang Theory: The Luminous Fish Effect (2007), he similarly states, "Uh, yes, but anyone who knows anything about the dynamics of bacterial growth knows to pick up their refrigerated foods on the way out of the supermarket."

Sheldon says he learned about football from the time he was five until the time he went off to college, and it was the longest seven years of his life, which would make him twelve. In earlier episodes, he claims he went off to college at the age of eleven. See more »

Sheldon Cooper: Excuse me. You're misusing the word "ho". It's an interjection used to call attention to a destination, not an object. As in, uh, "land ho!" or, uh, "westward ho!"
