Certain words have been suggested to be inherently funny. Vaudeville tradition holds that words with the letter k are funny. A 2015 study at the University of Alberta suggested that the humor of certain nonsense words can be explained by whether they seem rude, and by the property of entropy – the improbability of certain letters being used together in a word. The philosopher Arthur Schopenhauer posited that humor is a product of one's expectations being violated. (Realisation).
