Sometimes taking a hit to your property value is the just the right thing to do.
During my junior year at Temple, I had an elderly professor who was memorable for three main reasons. The first was that over the course of the 50 minutes, a small puddle of drool would slowly accumulate in the left corner of his mouth, precariously pooling there as the class looked on. Around the 30-minute mark, it would begin to visibly quiver as he spoke, and by the 45th minute, students were violently ducking out of the way as he walked by, for fear of entering the splash zone. Occasionally, we were fortunate enough to see it drop by the end of class, our faces twisting in horrific amusement as it soaked into his sweater.
