And then, for the rest of the semester, about once a week, we'd be talking about something much more rational and normal and someone would say, "I'm gonna put on the Tin Foil Hat" and share a bizarre thought or strange connection. It was a way to call attention to something that wasn't fitting in, something that couldn't be reconciled to the model of analysis we were using. Having that escape valve for conversations gave everyone license to shut up the superego of "don't overanalyze, you nerd."
