Bean Bags

There's so many different things called bean bags, you get the professional type huge bean bags that cost about £100 each then the more affordable sort that you'd have when you were a kid and you'd always jump on it till it'd eventually burst and there'd be beans everywhere and you'd be finding them for years to come. Then there's those little square ones you had at school, what the hell were they for? I seem to remember throwing them but surely a ball could be used for that. Very Strange.
Plus of course if you tipped some beans into a carrier bag you'd have to call that a bean bag too..... or i suppose calling it a bag of beans would suffice.
