Many have conjectured that the word "Duck" is the funniest word in the English language. This was popularized by the Marx Brothers comedy Duck Soup, considered by some to be the funniest movie ever made. This might have more to do with the actual animal than the English word for it, as in 2002, after conducting a scientific cross-cultural joke experiment known as LaughLab, psychologist Richard Wiseman concluded that ducks are funny in all the studied countries: "If you're going to tell a joke involving an animal, make it a duck."
