I remember I got an xray once...for kidney stuff. In those days, they used iodine (I think they use something else these days).
Anyway, there I was looking at the xrays with the guy who snapped the "pics". There was a good shot of my large intestine (or colon if you prefer). He pointed to the darkest parts and told me those were farts on the way and that the slightly lighter "lumps" were poop.
Looking back now, I'd have to say that was my most exciting xray ever!
