Friend 1: If I had the power to control time, I would probably just use it to sleep more
Me: If you stopped it during a test at the last minute, just wandered off, brought your notes in, finished it correctly, and put them back, that would be a good idea, too.
Friend 2: If you could stop time, you wouldn't do tests. You could just take stuff from shops and live off that.
Me: No. That's illegal.
