For some reason,

every thirty minutes or so, my accounting professor tears off a corner from any random sheet of paper nearby. He immediately crumples it up into a tiny ball and quickly puts it in his pocket. It’s as if he thinks he’s doing this fast enough so no one will notice.

How many balls does he have? What does he do with his collection of balls? Why does he collect these balls? Are there just paper balls, or balls of other materials as well? Why does he keep fondling his balls? Does he think no one notices his ball fetish? Do other people notice his ball fetish? Because he stops talking during this process, I wonder what thoughts are going through his head…
