As you may or may not know, pandas getting down n' dirty is a rare enough occurrence - mainly due to the fact that females are only receptive to mating a few days of the year, and males have a small penis relative to their body size. It's one of the reason that the panda population is so low.

That means when they do get down to business it's a big deal - and interruptions such as the below are not welcomed.

The footage was actually shot last year at the Wolong Giant Panda Nature Reserve in Sichuan, China, but is doing the rounds on Twitter in recent days. And let's face it - if it doesn't put a smile on your face, there's something wrong.

Alan, always ruining everything.
