a question, answered

What if The Fonz had chosen to express his approval not with his thumb but through semaphore, the language of flags?

Potsie: Fonzie, you cool with this?

Fonz: [places red flag at his side and yellow flag at 45-degree angle to ground; then shifts arms so red flag is parallel to ground, and yellow flag is at a 135-degree angle.]

Ralph: You still got it, Fonz!
