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!”
