Raymond Tusk and Frank Underwood in “Unfinished Business”

Raymond Tusk

Can I ask why you do that?

Frank Underwood

Do what?

Raymond Tusk

Tap your ring like that. I've seen you do it on TV. Two taps every time you get up from a table or leave a lectern.

Frank Underwood

Something my father taught me. It's meant to harden your knuckles so you don't break them if you get into a fight. It also has the added benefit of knocking on wood. My father believed that success is a mixture of preparation and luck. Tapping the table kills both birds with one stone.

Raymond Tusk

Your father was a peach farmer?

Frank Underwood

Yes, he was. Not a very successful one.

Raymond Tusk

Lack of preparation or lack of luck?

Frank Underwood

Lack of both. He was better at giving advice than following it.
