This is an oldie but a goodie based on a Backstreet Boy parody by Weird Al Yankovic, in case you missed it.
Did you look closely? This is not an official Weird Al video. It apparently was put together by a 12 year old back in 1999 (thanks to a Google of "Kronix Project") with a budget of practically nothing on some really basic slideshow software. Yes folks, link bait is that easy.
