What is the musical half of the children's song I am a little teapot:

Baby Bus - I am a little teapot

I am a little teapot

Short and fat

This is my handle

This is my mouth

When I fill it with boiling water

I just shouted

Put me up and pour a glass of water

I am a little teapot

Short and fat

This is my handle

This is my mouth

When I fill it with boiling water
