Do you know that eating dragonfruits, the purple ones, could cause your dump (and pee) purplish red? Almost like you're peeing blood. My friend experienced this for the first time about two years ago. At that time dragonfruits were not as vastly known as it is today. She said her heart almost stopped looking at the toilet bowl when was about to flush.

I, being an airhead I was, experienced the same mini heart-attack after forgetting said friend's warning when she saw me eating a purple dragonfruit for the first time.
