Even a few minutes of smiling is enough to help you feel better.

Norbert is a therapy dog that makes the rounds at Children's Hospital of Los Angeles with his owner, Julie. He has brought hundreds of kids peace by getting them to forget why they're in the hospital for just a few minutes. Norbert will help you forget your troubles for a few moments, too. It's impossible to see this little guy and not smile or laugh.
