A video called "Battle at Kruger" wins this year’s crown of most-viewed YouTube video. Twenty-one million people tuned in to watch an eight-minute clip of lions first fighting off an alligator for their supper only to be roughed up by a buffalo herd protecting a calf.

The video was taken at South Africa’s Kruger National Park.  

If that reality’s too stiff for you, then the video in distant second is decidedly limper. YouTubers watched Chris Crocker cry "Leave Britney alone!" about 14 million times. They were less enthused about him making out with his brother, but enjoyed countless spoofs, including Seth Green’s "Leave Chris Crocker alone!" send up, viewed at least 3 million times.

They’ve still got a ways to go, though, to catch "Evolution of Dance," which so far has racked up nearly 70 million views.
