Penny:
All right, Sheldon, this craziness has gone on long enough. Please come home so I can cut your hair.

Sheldon Cooper:
Penny, you're not trained, you're not licensed, and most importantly, you don't have access to my haircut records.

Penny:
All right, honey, look. We've known each other for a long time now, right? I've taken you to Disneyland, I kicked a bully in the nuts for you, I sing you "Soft Kitty" when you're sick, you've even seen me naked once.

Leonard Hofstadter:
I'm sorry, what?

Penny:
It's a long story. Anyway, Sheldon, I promise I know what I'm doing. Please let me cut your hair.

Sheldon Cooper:
Amy, what do you think?

Amy Farrah Fowler:
There's not a hair on my body I wouldn't let this woman trim.
