I am actually quite relieved that today I do not have to teach. Not because I don’t love my students and spending time with them, but because spending April 1st in a classroom can be a test of the most patient individual. April 1, colloquially referred to as April Fool’s Day, has historically been a day replete with pranks (harmless, annoying, and in some cases threatening). Pranking, however, has a long history. The Romans celebrated feasts to the goddess Cybele called Hilariae at the end of March. These festivals included pranking, telling jokes, revering rolls, etc. A common Medieval festival in April was the “Feast of Fools” (or other similar names). These were days of pranks, jokes, and hoaxes. Many cultures have a celebration of pranking and joking. Humor is a universal human experience.
