Sheet of Writing Paper = Lazy Dog

This is one of the most ridiculous and pointless proofs I've ever read:

Theorum: A sheet of writing paper is a lazy dog.

Proof: A sheet of paper is an ink-lined plane. An inclined plane is a slope up. A slow pup is a lazy dog. Therefore, a sheet of writing paper is a lazy dog.

Q.E.D.

Now, when someone tells you that a sheet of paper is not a lazy dog, you'll have this silver bullet in your barrel. I think a part of my logic died after posting this.
