The leader out of the gate for best commercial at Super Bowl XLV is a Volkswagen ad featuring a young Darth Vader. The most controversial? HomeAway's " Test Baby," which features a baby slamming into a glass wall as a joke.

But the race isn't over yet. Many of the commercials set to debut during the Big Game have already leaked online. Since the rise of YouTube, companies have made it a habit to publish their ads early, both to build buzz and control where people end up clicking.

So instead of waiting until Sunday—when everyone at your party will only distract you from the commercials that everyone will be talking about at work on Monday—check them out now and tell us your favorites. We've also included some "teaser" ads that are being used to promote the main ad that will air during the game.

The videos are below.
