One, two, three, four, five, six pox
Rest your wings
Seven, eight, nine, ten
As I count your green things
Eleven, twelve and thirteen pox
Now close your eyes
As I count fourteen green dots on your thighs

Fifteen and sixteen
Now hang your head low
Seventeen pox, eighteen
On your big toe
Nineteen and twenty
To sleep now you'll fall
And I've counted twenty
Twenty bird-pox in all
Yes, I've counted twenty
Twenty bird-pox in all
