There has been a spike in XXX parodies in the past few years. If there's a popular show or movie, you can probably bet on a pornographic version floating around somewhere in the ether. 

What's impressive is the amount of effort that actually goes into them. It's like you're watching the original version but with more blowjobs and surprisingly, better camera quality.
