I had a good one today - the little orange spots on my car which I'd previously thought were pollen (half right) are actually liquidfied nectar... from the anus... of a bee, i.e. bee turds.
Even better than that, apparently they may also be bee diarrhoea as they get infected with some sort of parasite. Sometimes they seem to be twice the length of a bee so its the equivalent of a 12 foot human shit. Nice.
