Doctor, Doctor, I can't get to sleep.
Sit on the edge of the bed and you'll soon drop off.

Doctor, Doctor You've got to help me - I just can't stop my hands shaking
Do you drink a lot?
Not really - I spill most of it!

Doctor, Doctor I keep thinking I'm a woodworm
How boring for you!

Doctor, Doctor I think I'm a bridge
What's come over you?
Oh, two cars, a large truck and a coach.

Doctor, Doctor I think I'm an electric eel
That's shocking!

Doctor, Doctor I think I'm a python
You can't get round me just like that you know!
