Okay, so this is definitely not timeless, but it's not forgettable either. A San Francisco couple did a 'Gangnam Style' send up for their wedding video (which is apparently something people make now).

They went all over the city and recreated scenes from the music video, in addition to getting their entire wedding party in on the fun. Be sure to watch the whole thing so you can see the bloopers kindly included at the end.
