To start, don't bother denying anything to your boss. He saw what happened, so don't insult his intelligence by spouting off a bunch of excuses he won't believe. And don't try to argue that everyone else slacks off, too - it won't win you any favors with the boss or with your coworkers. Instead, admit that you were caught blowing off your work, apologize and promise not to let it happen again.
Once you've said you're sorry, it's important that you stick to you word to avoid a similar situation in the future. While it's usually okay to take a few minutes to check out your favorite sports news website or see if you have any new voicemails, always keep your breaks short and sweet - don't get so sucked into your activity that you forget what you're actually on the clock for! Your job is your top priority, so treat it that way.
