    “Will you walk a little faster?” said a whiting to a snail. \
    “There's a porpoise close behind us, and he's treading on my tail. \
    See how eagerly the lobsters and the turtles all advance! \
    They are waiting on the shingle---will you come and join the dance? \
    Will you, won't you, will you, won't you, will you join the dance? \
    Will you, won't you, will you, won't you, won't you join the dance?

    “You can really have no notion how delightful it will be \
    When they take us up and throw us, with the lobsters, out to sea!” \
    But the snail replied “Too far, too far!” and gave a look askance--- \
    Said he thanked the whiting kindly, but he would not join the dance. \
    Would not, could not, would not, could not, would not join the dance. \
    Would not, could not, would not, could not, could not join the dance.

    “What matters it how far we go?” his scaly friend replied. \
    “There is another shore, you know, upon the other side. \
    The further off from England the nearer is to France--- \
    Then turn not pale, beloved snail, but come and join the dance. \
    Will you, won't you, will you, won't you, will you join the dance? \
    Will you, won't you, will you, won't you, won't you join the dance?”
