+Jabberwocky
+BY LEWIS CARROLL
+’Twas brillig, and the slithy toves
+      Did gyre and gimble in the wabe:
+All mimsy were the borogoves,
+      And the mome raths outgrabe.
+
+“Beware the Jabberwock, my son!
+      The jaws that bite, the claws that catch!
+Beware the Jubjub bird, and shun
+      The frumious Bandersnatch!”
+
+He took his vorpal sword in hand;
+      Long time the manxome foe he sought—
+So rested he by the Tumtum tree
+      And stood awhile in thought.
+
+And, as in uffish thought he stood,
+      The Jabberwock, with eyes of flame,
+Came whiffling through the tulgey wood,
+      And burbled as it came!
+
+One, two! One, two! And through and through
+      The vorpal blade went snicker-snack!
+He left it dead, and with its head
+      He went galumphing back.
+
+“And hast thou slain the Jabberwock?
+      Come to my arms, my beamish boy!
+O frabjous day! Callooh! Callay!”
+      He chortled in his joy.
+
+’Twas brillig, and the slithy toves
+      Did gyre and gimble in the wabe:
