Bat fluffers

I saw this article a while ago but then promptly forgot about it, however it cropped up again today, it's such a great piece of research that I just have to share it (where do these people get grants like this from??) Anyway, the subject is "Bat fellatio", it seems unlikely that anyone other than cat woman would utter those two words together but apparently our furry little cousins indulge in a bit of oral now and again too!

The purpose of this behaviour appears to be to prolong intercourse, you can read all the gory details here but essentially 14 out of 20 bat copulations filmed involved a blow job, on average it lasted roughly one twelfth the time of the entire act and those couplings that involved fellatio lasted approximately twice as long as those without.

I wonder if it would be "PC" to leave this research paper lying around the house?
