Why can't a panda be more like a frog....?

Thinking about the sexual plight of the poor old pandas at Edinburgh Zoo reminded me of the orgy I witnessed along the canal between Wendover and Tring about a week ago. A shallow pool had formed where they have built a dam across the drained stretch of canal and these fellas were 'at it' big time. Toads and frogs were there and just grabbing anything else that moved.....taking pictures didn't seem to put them off at all!!
