Use Audacity to delete unwanted parts to create a good read of this stanza

`Twasbrillig, and the slithytoves;Did gyre and gimble in the wabe:All mimsy were the borogoves,And the momerathsoutgrabe
"Beware the Jabberwock, my son!The jaws that bite, the claws that catch!Beware the Jubjub bird, and shunThe frumiousBandersnatch!"
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 throughThe vorpal blade went snicker-snack!He left it dead, and with its headHe went galumphing back.
"And, has thou slain the Jabberwock?Come to my arms, my beamish boy!O frabjous day! Callooh! Callay!He chortled in his joy.
