The Mischief Maker's Manual, a hilariously illustrated book, was written for kids but is great for anyone who still laughs at fart jokes and loves pulling pranks. You might want to read it first, so you know to watch out for the "Diet Coke Explosion" trick, and the "World's Largest Butt Photo." But even if you get duped by the "Invisible Toilet Force Field" prank, try to laugh and roll with the punches -- it just means your husband is having a blast.
