Before It Gets Old: Nirvana vs Rick Astley, 'Never Gonna Give Your Teen Spirit Up'

Just when you thought you've witnessed every possible permutation of the Rickroll, from the Barackroll to Beaker of the Muppets singing "Never Gonna Give You Up," here comes a clip to, however briefly, breathe new life into the grizzled viral video genre. Like all the best mash-ups, it's spooky how well the tempo changes have been matched up--and the video, too, with Kurt appearing to sing along with "tell a lie" at 1:03. Alright Rick Astley, we'll watch you one more time. But this is it! Honest. (Maybe.) Mash-up is by DJ Morgoth, video by Thriftshop XL.
