He allegedly composed this sentence impromptu.
The great Panjandrum
by Samuel Foote
When a certain Charles Macklin claimed he could repeat any sentence he heard, no matter how complex, Samuel Foote allegedly composed this sentence impromptu:
So she went into the garden
to cut a cabbage-leaf
to make an apple-pie;
and at the same time
a great she-bear, coming down the street,
pops its head into the shop.
What! no soap?
So he died,
and she very imprudently married the Barber:
and there were present
and the Joblillies,
and the Garyulies,
and the great Panjandrum himself,
with the little round button at top;
and they all fell to playing the game of catch-as-catch-can,
till the gunpowder ran out at the heels of their boots
