Ha! Back when I was using iTunes, I was at work and decided to see what other libraries were being shared. A certain PhD student was sharing his library, and since he was a decent dude, I decided to see what his collection was like. I quickly realised that he probably didn't know it was being shared- the whole library was porn videos that he'd downloaded. Stupid thing is that iTunes couldn't even decode the Xvid codec they were encoded in, but I could certainly play the mp3 sound back on my machine!
In fact the only way I figured out what his "collection" was was when I tried to play an interestingly named file - I honestly thought "Gangbangers" must have been an old-skool (mid-90s, so not
really old-skool) rap crew. I immediately went up to him in the other side of the facility and told him to stop sharing his library.
Funnily enough he won a pretty prestigious award as a promising young researcher two weeks ago, having made big strides in understanding the molecular basis of schizophrenia. Thus, it provides a strong case that porn makes you more productive.
