Pets and the holidays

Many people give their pets treats for the holidays. But do the pets know that the day is special? How do they let you know how they feel, when they're happy?

Those who believe that they can communicate with their dogs, cats and other pets don't always agree on how that communication works - whether it's emotions, gestures, or images. What do you think?

In the last thirty years, a new breed of magicians has entertained us. In 1974, Doug Henning starred on Broadway in the musical The Magic Show. Four years later, street magician Jeff Sheridan published Street Magic - An Illustrated History of Wandering Magicians and Their Conjuring Arts. Web magic sites started with magic stores in 1994. David Blaine's first TV special appeared in 1997; his latest was only a few weeks ago. David Copperfield and Penn and Teller have appeared almost non-stop in Las Vegas for years, along with Criss Angel and others.

Who's your favorite magician today? Who would you have liked to see perform in the past?
