The 1994 classic buddy comedy, Dumb and Dumber, is known for its quotable moments, toilet humor, and the irony that is wasted on the main characters, Harry (Jeff Daniels) and Lloyd (Jim Carrey) on a cross-country road trip. You probably know at least one catchphrase from the movie, but did you know it was originally an incomplete script conceptualized by filmmaker John Hughes? He ended up selling it to The Farrelly Brothers — Peter Farrelly and Bobby Farrelly — and then asked the filmmaking siblings that he not be credited for it. Before the release of Dumb and Dumber, the Rhode Island natives were newcomers who had written some screenplays, including several episodes of Seinfeld and an unaired sequel to Dragnet. However, Dumb and Dumber was their first feature film that went onto gross-out comedy status to become a blockbuster, grossing more than $243 million at the box office. The filmmaking pair was immediately known for their more vulgar, slapstick brand of comedy that features working-class, average Joes in the spotlight.
