Isaac, the beloved

Isaac has been substituting at my school for a friend of mine. A whole bunch of my AP students are also in her English classes, so they have had Isaac all week. They've finally figured out that we are 'related'-I thought it was rather entertaining that it took them a week to figure out, but whatever- and now all I hear about is "Mr. Montague is so cool" or "I wish Mr. Montague was our teacher all the time." They have even requested that he be my sub when I go to Texas next month. How does he do that?!
