Try cutting open the bottom of your settee and then post pictures on here of the stuff you've found.
See how long you can talk like Roger Rabbit without drooling all over yourself.
My personal favourite (I have actually done this although the 'list' is sitting at my mate's house) ...

I call it my 'Dry as **** list'.
Items include refried beans, Cadbury's flakes, weetabix, swiss rolls, Galaxy ripples, iced gems, black pudding etc
