You Ever Found Out Something About Someone Later In Life?

Have you ever had a relative or a family friend you knew all your life, but when you get older you find out some shite about them that you would have never guessed?

Had a great uncle who was single.. This wasn't really finding out anything about him, but after he died.. I was about 10 or 11. And I saw that he had one of those pens that has a picture of a woman inside of it and if you shake it her top comes off. But later my brother told me they also found a stash of nudie mags and tapes of what was probably porn. I just never thought of him as a horny old man..

But have you ever learned later in life someone you always knew, went to jail or did some crazy shite back before you were born?
