Ok, this is a bit of a random mystery. I was reading in the garden the other weekend, went to make a cup of tea and when I went back outside, half a human poo had appeared on the grass. I panicked a bit and got rid of it before I took a photo, so I’ve recreated the scene using felt tip pens.
My first thought was that it fell from a plane. This can happen; (http://bit.ly/heSIdo)
