A common cliché is that, if presented with a large and expensive new toy, a child will quickly become bored with the toy and play with the box instead. Although this is usually said somewhat jokingly, children certainly enjoy playing with boxes, using their imagination to portray the box as an infinite variety of objects. One example of this in popular culture is from the comic strip Calvin and Hobbes, whose protagonist, Calvin, often imagined a cardboard box as a "transmogrifier", a "duplicator", or a time machine.
