Here’s a rhyme I picked up somewhere:

Blue bells, cockel shells, easy ivy over,

I met by boyfriend at the candy store
He bought me candy, he bought me cake,
He brought me home with a tummy-ache…

Mama, mama, I’m so sick,
Call a doctor, quick quick quick!

Doctor, Doctor, will I die?
Count to five and you be all right.

1 2 3 4 5 I’m alive!
