I sent the link to this story to my dad (a retired science teacher). He enjoyed it--and he passed the link on to several of his friends.


"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.”
