Quotes for T-shirts, Buttons and MERCH!

What do you think about book-related merchandise? I fully realize that this is stuff that is most appealing to a market of one (me). But if it's not too expensive to print up a few somethings with quotes or images or whatnot, it would be fun to have/sell/give, I think. I'm already looking forward to doing a book signing/launch party at the little bookstore in downtown Roanoke (Book No Further) where the only person who will come in is the unhomed guy who walks around downtown without shoes. He likes books.

Possible quotes and ideas below. Any of them sound particularly good or bad?

1. This is point of science, yes?
