The Serenity Now Season 9, Episode 3

Frank

Like an animal. Because of her, I have to sit here like an animal! Serenity now! Serenity now!

George

What is that?

Frank

Doctor gave me a relaxation cassette. When my blood pressure gets too high, the man on the tape tells me to say, 'Serenity now!'

George

Are you supposed to yell it?

Frank

The man on the tape wasn't specific.
