In the pilot, life is about to change for two geniuses, Sheldon and Leonard when the beautiful Penny moves in across the hall. Leonard sees potential love interest in Penny and offers to retrieve her television from her ex-boyfriend.
Sheldon: Why do you have the Chinese character for "soup" tattooed on your right buttock? Penny: It's not "soup," it's "courage." Sheldon: No it isn't. But I suppose it does take courage to demonstrate that kind of commitment to soup. Penny: How'd you see it? You said you wouldn't look. Sheldon: Sorry. As I told you, the hero always peeks.
