Tim and the Doctor

Doctor: Good morning! Who is this?

Dad: Good morning, Doctor. This is my son, Tim.

Doctor: Hello, Tim. How old are you?

Tim: I’m seven.

Doctor: Seven! OK. What is it? Is it his head? Is it his nose?

Dad: No. It’s his ear.

Doctor: His ear? What is in his ear? It’s money!

Dad: Money?

Doctor: Whose money is it?

Tim: It’s Dad’s money.

Dad: My money? Tim!

Tim: Sorry, Dad. There is more money in my nose.
