What is the strangest way you have injured yourself?

I ask this question after somehow managing to cut the roof of my mouth with a bit of my breakfast cereal this morning as I am sure that Kellogs do not have to put a warning on it that eating their product may result in an injury.

This then got me to thinking about other strange ways that humans can hurt themselves, so how about you? Have you put your back out through farting? Have you split your head open in a strange way? Have you ever actually managed to fall on a banana skin?

The A&E department is now open.
