The Wall Street Journal has a front page story today about getting boys to read by using the grossest subjects possible, including putrefying wounds, farting, rats, toilets, and lots of blood.
I am glad to see Captain Underpants still on the list of popular books for boys. But I think the WSJ story misses one key element: humor. Boys want humor in their books and the lower and sillier the humor, the better. Even the gross books have to have a sense of humor about the subject to work best.
Captain Underpants works because of the silliness, not the gross-out factor. Jeff Kinney's very successful Diary of a Wimpy Kid works because of the humor. And even older funny books like Judy Blume's Tales of a Fourth Grade Nothing will be adored by modern kids. It's the giggles that keep them reading, especially in the summer.
