This YouTube video is spreading like a wildfire, so you’ve probably already seen it. (I discovered it through Peter Chattaway’s blog.)

If not, here it is: the funniest YouTube link in, oh, at least a few weeks.

It’s sure to inspire a ton of variations, and that could be a good thing… it’s such a simple and brilliant idea. Basically, it’s a bunch of footage from Star Wars in which James Earl Jones’s lines as Darth Vader have been replaced by his lines from other films. You’ll never look at Vader quite the same way again.

But proceed with caution: There’s some harsh language involved.
