I just read this on the archives, and it was hilarious! It took me a while to figure out that Clark was a dog.

I love the ending -- Lex turning into a dog and being sent to a shelter where the dogs are all neutered.

"Oh, you can’t help that," said the Cat: "we’re all mad here. I’m mad. You’re mad."
"How do you know I’m mad?" said Alice.
"You must be," said the Cat, "or you wouldn’t have come here.”
