This is reminding me of a time in school were we thought if we stole all the chalk we might get a day off of Calculus class.

The professor came in and looked around for two minutes before shrugging and pulling a fresh stick of chalk out of his back pocket and began writing on the board.

This is the same professor who we'd never seen use a fresh piece of chalk ever, he always just soldiered through the nubs and remains littering the board's chalk tray.

We had no idea he actually kept a pack of sticks in his back pocket at all times.
