The Laugh Bag (aka Laugh Box, Laughing Bag) has been around for many years. It has always been a favorite gag toy. The laugh box is a simple plastic box, when you press the button, it starts laughing at a loud pitch and volume, laughing uncontrollably. It's infectious and all around will begin to laugh. Batteries included. Great fun at dinner parties, get-togethers, school cafeterias and more!
