Are they giving him variety? Variety is key.

Maybe that’s the problem. How much variety within this genre can there really be?

Chuang Chuang the panda has been spending his days in front of a big screen television watching panda porn.

Authorities at the Chiang Mai Zoo in northern Thailand hope the images will encourage him to mate with his partner, Lin Hui, and serve as an instructional lesson in how to do it right.

So far, it’s been a tough sell, the zoo’s chief veterinarian, Kanika Limtrakul, said Tuesday.

“Chuang Chuang seems indifferent to the videos; he has no reaction to what he’s seeing on TV,” Kanika said. “But, we’re continuing to show him videos and hoping they will leave an impression.”

Exit question: Maybe the porn pandas are so attractive that he’s not into Lin Hui anymore? Just tellin’ you what I hear, buddy.
