It seems a strange notion to me to assign any set of criteria to what makes something funny. Looking back as far as we can through our brief and transitory place in history, the place of comedy has been ever-present and ever-changing. We can observe this over the course of a few hundred years. I defy anyone between the ages of 18-30 (I suggest these parameters as they are the most inclined to be influenced by the most current forms of comedy) to read any of the frequent literary wit in Shakespeare’s portfolio and genuinely cackle.
