1. Do not wipe up a coffee spill with a sock. It is impossible to wash coffee out of a sock, and that is why I look like I'm wearing some sort of cowhide on my left foot.
2. Do not let students pick the topics when you're trying to challenge the idea that some things are simply undebateable. I let them pick the things that their opponents would have to try to defend, and they fired off things like genocide and child prostitution. It seemed for a minute like we were going into Lord of the Flies territory, and then they made it as classy and inoffensive as an exercise like this could possibly be. It doesn't change my suspicion that they would emerge as the rulers if this program was put in some sort of state of nature scenario, but I was still impressed.
