Little Miss Mufti…? She shat on Ed Tufte.
Little Jack Horace…? He shat on Chuck Norris.
Little Brass Ambo...? He shat on John Rambo.
Little Blow Peep...? On Uriah -- young Heep.
Brave Little Toot shat on George Frederick Root.
Grave Little Nell shat on Patti LaBelle.

But fat Mrs. Spratt gave no shit where she shat.
