Sketch 2

A: Augh! B: Whatever is it, man? A: It’s my leg, Doctor.

B: This looks nasty. I shall have to amputate. A: It’s the one you amputated last time, Doctor. B: You mean you’ve got a pain in your wooden leg?

A: Yes, Doctor. B: You know what this means? A: Not woodworm, Doctor!

B: Yes. We’ll have to remove it before it spreads to the rest of you.

(A’s chair collapses) B: My God! It’s spreading to the furniture! (And so on).⁴⁴  

In Sketch 3, actor A does a bit of initial ‘blocking’ – refusing to pick up B’s notion that they may have met ‘at the yacht club’, but quickly recovers and offers a fruitful new direction: ‘School!’
