Leonard Stern â€” a prolific television writer, producer and director â€” died Tuesday at age 88. Among his credits: a writer for The Honeymooners, Get Smart and McMillan and Wife â€” to name a few. Yet, his most enduring contribution may not be found in punch lines for the small screen â€” but rather in blank spaces. Stern co-created the popular word game Mad Libs with fellow comedy writer Roger Price in 1958. At the time of the game's 50th anniversary, more than 110 million copies reportedly had been sold. Melissa Block and Michele Norris remember Leonard Stern.
