They look a bit like the baby alien when it comes out of John hurt's chest.
A few years ago, on the ferry back from Bilbau to Portsmouth, and after a fortnight of eating anything that looked edible, I laid a log which was so big, it looked like it was trying to climb out of the toilet. I called Mrs. P to "come have a look and bring your camera".
She wasn't as impressed as I thought she would be and years later, she still goes on about it
