I'm a pleasant mother pheasant plucker. I pluck mother pheasants. I'm the fastest pleasant mother pheasant plucker ever plucked a mother pheasant in the whole wide world.
I've always done a different version of that:
I am not the pheasant plucker, I'm the pheasant pluckers son, and I'm only plucking pheasants, till the pheasant plucker comes.
I think one of my faves is:
What a to do, to die today, at a minute or two till two.
A thing distinctly hard to say but harder still to do.
For they'll beat a tattoo, at twenty til two,
with a rat-tat-tat-tat-tat-tat-tat-tat-tattoo
And the dragoon will come
to the beat of a drum
at a minute or two till two today,
at a minute or two till two.
