Background
We have a discussion about what happened (a cell phone goes off in a lecture hall; the interrupted professor takes it, then slams it to the ground before continuing with his lecture), and students' responses. Several say that student deserved to have his phone destroyed. Some say the professor should have taken the phone, but not broken it. Others say the professor was out of line completely. It's usually a spirited debate.
Then, we get to the assignment.
