One of the best-known kettle rhymes in the language: Polly puts it on, Sukey takes it off again. The repetition and the mime of pouring tea make it a natural for little hands to join in.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Polly, put the kettle on,
Polly, put the kettle on,
Polly, put the kettle on,
And let's drink tea.
Sukey, take it off again,
Sukey, take it off again,
Sukey, take it off again,
They're all gone away.
