This is quite possibly the most popular poem from Alice in Wonderland, and maybe it's popular for the same reason that 'Supercalifragilisticexpialidocious' became popular in Mary Poppins. There's something really wonderfully fun about completely made-up, almost atrocious words ? and this poem is full of them.
The jaws that bite, the claws that catch!
Long time the manxome foe he sought—
And, as in uffish thought he stood,
The Jabberwock, with eyes of flame,
Came whiffling through the tulgey wood,
And burbled as it came!
The vorpal blade went snicker-snack!
’Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.
