Scratch

Scratch is hard at work developing the next big mathematical theorum. The issue he's running into lately is that all the good letters are already taken: y=mx+b, E=mc^2. So he's reciting the alphabet over in his head in hopes inspiration will strike. It's important work.

Scratch is ____ inches tall and ____ inches across. He doesn't have much time to think about what he might like to hold. Luckily black goes with everything.
