Beware of the day

If your Snark be a Boojum ...

... for the Snark was a Boojum you see.

You may seek it thimbles - and seek it with care;

You may hunt it with forks and hope;

You may threaten its life with a railway-share

You may charm it with smiles and soap ---

But oh, beamisch nephew, beware of the day,

If your snark be a Boojum! For then

You will softly and suddenly vanish away,

and never be met with again!

Lewis Carrol, "The Hunting of THE SNARK".
