"By the way, Pooh, how do you spell Tuesday?"
"Spell what?" asked Pooh
"Tuesday. You know - Monday, Tuesday..."
"My dear Pooh," said Owl, "everybody knows that it's spelled with a Two."
"Is it?" asked Pooh.
"Of course," said Owl. "After all, it's the second day of the week."
"Oh, is that the way it works?" asked Pooh.
"All right, Owl," I said. "Then what comes after Twosday?"
"Thirdsday," said Owl.
"Owl, you're just confusing things," I said. "This is the day after Tuesday, and it's not Thirds - I mean, Thursday."
"Then what is it?" asked Owl.
"It's Today!" squeaked Piglet.
"My favorite day," said Pooh.
