The Carburetor

- The car won't start - said a wife to her husband.

- I think there's water in the carburettor.

- How do you know? - said the husband scornfully.

- You don't even know what the carburettor is.

- I'm telling you - repeated the wife.

- I'm sure there's water in the carburettor.

- We'll see - mocked the husband.

- Let me check it out. Where's the car?

- In the swimming pool.
