I had a 28 litre keg of home pressed cider in the garage. Pretty powerful stuff. I would let my lad have a small amount at the weekend under my supervision...or so I thought. One Friday night I went upstairs to find him in the bathroom with about 4 pints of it along with what he had eaten for tea all over the floor. 
Something similar happened to me and a friend with my older brothers homebrew in the 80's
I have never been in the same state since thanks to that.
