the perfect lines

What is the perfect thing to read when you are working on the demonstratives, in winter, and on a Tuesday?

On Tuesday, when it hails and snows
The feeling on me grows and grows
That hardly anybody knows
If those are these, or these are those

A. A. Milne, Winnie The Pooh

(p.s. I cheated this off a paper on demonstratives)
