The idea of the Dryoff Book Series came from a joke contest he held in his classroom on Monday mornings. Students would submit jokes in a cardboard box placed in the classroom, appropriately named the "dry box". Lanehart would choose five jokes from the box to read to the class, who would then grade them on a scale of 1-10, according to the dryness of the joke. The student whose joke received the highest number at the end of the day would receive a new, straight from the custodian's office, never been used, brown paper towel, autographed with their name and the words "Dry Off." The idea behind the paper towel was that you never knew when you might have to dry off. Lanehart has written The Dryoff Book 1: The Mysteriously Silly Solo Edition, The Dryoff Book 2: The Dynamically Dumb Duo Edition, and now The Dryoff Book 3.0 for Smarties. These books consist of a compilation of all of the jokes that have been submitted. He has tried to engage his readers young and old, to enjoy the refreshing and innocent feeling dry humor can bestow. He has meticulously illustrated many of the jokes with clipart to give the jokes more of a "dry feeling." This is the third of four books, with The Not So Dryoff Book 4: The Critically Ashamed Insensitive Edition as the last in the series.
