During the holiday season we all strive to focus on the positives, such as good will, cheer and plenty of egg nog. But this year we decided to shed light on a potentially serious problem: the number of emergency room visits the holidays can cause, from electrocution via Christmas lights to slipping on ice, breaking your limbs from falling off the roof in a rented Santa Claus costume, etc. etc.

We have compiled some of the best and most painful accidents in holiday movie history. Here's hoping this video will prevent at least a few Christmas Eve visits to the hospital -- and give you a laugh or two at Tim Allen's expense.
