Panda Porn

Apparently porn can be used for educational purposes:

On the trivial side, pandas in captivity sometimes are not successful at mating. Usually, this is due to lack of experience. In order to tackle this problem, keepers of the bears in China have been known to show "pornographic/educational" videos to the bears, the contents being pandas having sex with each other. Amazingly, the bears get stimulated by the videos. However, it is not likely that they learn from the video itself; rather, scientists believe that the audio content of excited pandas has an impact on the bears exposed to it.

I find this amazingly interesting. I mean, who knew that porn was the universal foreplay? When it comes down to it, though, couldn't they just play a CD of pandas doing it?
