I make personal appearances around the country. I'm starting a book tour now, and I may be coming to Toronto with the Learning Annex, which I'm doing all through the United States, so that may come up just before Christmas.

I love all things Christmas.

I love cooking during Christmas, all smells like the hot apple cider, the hot spiced wine.

South Park started as a little video Christmas card.

The Earth reminded us of a Christmas tree ornament hanging in the blackness of space. As we got farther and farther away it diminished in size. Finally it shrank to the size of a marble, the most beautiful marble you can imagine.
