Guise tests: What is 10! ? It's a fairly large number, and I have it memorized. There are two pairs of consecutive digits that are the same.

My summer reading book, who the author is, and the publisher. The book has 3 words, and it starts with an 0. the publisher is Penguin. It's not a well known author. He's lived more than two thousand years ago, so his name will be pretty odd.

My alt. It has 11 letters and starts with d. There are 2 capital letters in it.

Almost anything math related. (That probably won't work very well, but you can try it.)

The picture is "pottage." It's not just soup.
