Confirmed: Bad jokes are the result of mental illness

Witzelsucht (the Germans just have the best words for everything, don’t they?) is a brain dysfunction that causes all sorts of compulsive silliness: bad jokes, corny puns, wacky behavior. It’s also sometimes called the “joking disease,” and as Taiwanese researchers phrased it in a 2005 report, it’s a “tendency to tell inappropriate and poor jokes.” We’ve covered all sorts of strange disorders of the mind in earlier Body Odd posts: one disorder makes you believe your loved ones are strangers, another convinces you that your hand has taken on a life of its own. Now, we give you a brain disorder that actually causes a poor sense of humor.
