In other words, in Calvin's eyes, Hobbes is alive while the rest of the world, including his Mom and Dad, see a stuffed tiger. They pretty much go along with this and put it down to childish imagination.
It's funny because the first Calvin and Hobbes collection I picked up and began to read many years ago, it was not until about a third of the way through they showed a strip that had an adult in the picture and Hobbes was thus revealed to me as a stuffed animal! I had been thinking What is going on here with this kid and his tiger!
In spirit of yesterdays entry which was a Flintstone's 'ever so wrong' video, here today is one for Calvin and Hobbes. I would suggest if you are not familiar with the strip, and you want a really, really good laugh, read through the Wikipedia article linked above before viewing.
