In a Lewis Carroll's nonsense poem, who "came whiffling through the tulgey wood"?

It's the "Jabberwock."

“Jabberwocky” is the name of the poem.

I read he suffered migraines and a speech impediment (stuttering) but I believe opium was also a part of his life.

bhblues, I loved Alice in Wonderland and Through the Looking Glass.

loco, no, it was only directed by Terry Gilliam and Michael Palin played a role but none of the other Pythons were involved.
