How come "burbled" gets to be in the Oxford English Dictionary but "tulgy" doesn't? Hm?

Lewis Carroll. He was an odd one. Real name was Charles Lutwidge Dodgson. Completely denied having anything to do with the Alice books. Daft as a brush. You'd have liked him!

...Is Wonderland really a wonder...when you have nowhere to land?

ALICE
She drank from a bottle called DRINK ME
And she grew so tall,
She ate from a plate called TASTE ME
And down she shrank so small.
And so she changed, while other folks
Never tried nothin' at all.

Alice:How long is forever? White Rabbit:Sometimes, just one second.

Curiouser and curiouser!
