“Humor, it is a difficult concept.”
— Star Trek II: The Wrath of Khan
Being funny on the printed page looks easy but is deceptively difficult. Writers like Terry Pratchett and Douglas Adams make it look so easy, when it reality it can be very, very difficult. Just look at the myriad of people out there who have tried to be funny like Pratchett and Adams are, but just don’t quite make it.
