When I was at boarding school, being the kind "caring" prefect- i.e. the one who play boxes, but gets away with it- I gave the kids (40 odd) some biscuits I had 'made', i.e. stored as I came back from ATC expeditions and the like.
It was my last week, so I didn't give two hoots what was going to happen, as long as I got my A-Levels, that was fine.
So on the third day (the day I was leaving) after giving them the biscuits, all the loo-paper dissappeared.
Mind you, more biscuits turned up.
Hmmm, where did they go?
Needless to say, the "biscuit browns" went down a treat.
