What is the most far fetched excuse you've heard someone make which turned out to be true ?

I have a good one, my best friend had a scrapped leg that looked like what would happen to someone if the person took a fall, he denied and said he accidentally did that while scratching his leg with a tv remote. I called bullshit, he became annoyed, went back to his house, got the controller and much to my horror proceeded to do the same thing in the other leg using the burrs his controller's side.
