Now from 9 double to 8 double,

And from 8 double to 7 double,

And from 7 double to 6 double,

And from 6 double to 5 double,

And from 5 double to 4 double,

And from 4 double to 3 double,

And from 3 double to 2 double,

And from 2 double to 1 double,

And from 1 double to no double,

No double hath he!”
