Enough of these comedy facts DD, here's a real one...
Karl Marx was at one time known as the "fifth" Marx brother and was greatly responsible for the creation of his brother Groucho's comedy persona with quotes such as "Catch a man a fish, and you can sell it to him. Teach a man to fish, and you ruin a wonderful business opportunity".
He was asked to leave the group when it became clear that his "Comedy Manifesto" differed greatly from that of Groucho, Harpo, Chico and Zeppo, but his parting comment "Last words are for fools who haven't said enough" was the inspiration behind Harpo's silent act.
