Children's rhyme and movement routine, much parodied. The original goes:

I'm a little tea pot, short and stout
This (put one hand on hip) is my handle,
This (hold other arm out, bent at the elbow with hand pointing up) is my spout.
When I get all steamed up, hear me shout!
Tip me over (bend at waist so that "spout" arm moves downward) and pour me out.
