Big Bang Theory Quote
Penny: You know, Sheldon, I used to cut my brother's hair. I could do it for you.
Sheldon: Penny, I know you mean well, offering the skills of the hill-folk. But here in town we don't churn our own butter, we don't make dresses out of gunny sacks, and sure-as-shootin' don't get our hair cut by bottle blonde...
Leonard: (interrupting) Sheldon, be nice!
Sheldon: I'm sorry. It's the bad boy attitude that comes with this hair.
