From DR. BOLI’S ALPHABET OF OCCUPATIONS.

Y for the Yes-man, who longs to say “no”;
Alas and alack, in his job it’s prohibited.
Original thought
Is not what he’s here for,
So let’s give a cheer for
The Yes-man who really would like to say “no,” but does not.

The job is a hard one, as Yes-men all know:
His private opinions may not be exhibited.
His job is to say
What his bosses will pay for,
So let’s say hooray for
The Yes-man who’d rather say “no,” but says “yes” anyway.
