As mentioned in the comments below, if you're stuck at work today and love the U.S. Open, you can pretty much watch the whole thing live in HD on your computer at USOpen.com. We have a Mac, which isn't always the best at playing video, but the reception on this is clear and free of burps.
So, you can spend your workday watching golf. That's an easy way to get through the day, though be careful not to fall asleep.
