Quote from Phoebe in The One with All the Resolutions
Joey: All right, Phoebe, I am ready for my first lesson. Phoebe: No, you don't touch the guitar. First you learn here, then you learn here. Joey: Okay. Phoebe: Okay. Lesson one: Chords. Now, um, I don't know the actual names of the chords. But I made up names for the way my hand looks while I'm doing them. So then this is "Bear Claw", "Turkey Leg" and "Old Lady."
