From Carnival of the Animals:
Tortoises
Come crown my brow with leaves of myrtle,
I know the tortoise is a turtle.
Come carve my name in stone immortal,
I know the turtoise is a tortle.
I know to my profound despair
I bet on one to beat a hare.
I also know I’m now a pauper
Because of its tortley, turtley, torpor.
Music by Saint-Saëns, words by Ogden Nash, read by Noel Coward. Great Album.
