According to the official website (see below), "National Humor Month was founded in 1976 by best-selling humorist Larry Wilde, Director of the Carmel Institute of Humor. It is designed to heighten public awareness on how the joy and therapeutic value of laughter can improve health, boost morale, increase communication skills and enrich the quality of one's life."
Why April? Mr. Wilde responds on his website: "Since April is often bleak and grim and taxes are due on the 15th, it can be one of the most stressful times of the year," says Wilde, author of 53 books on the subject of humor. "Besides," adds Wilde, "it's the only month that begins with All Fool's Day -- a day which has sanctioned frivolity and pranks ever since the 1500's."
