ok this is the deal. I was at a little tourist shop in Liverpool with my mate once and i noticed he was having trouble breathing. Turns out he was just strugling for air through laughing so much! This is what he'd spotted. it's a little piggy bank type thing. You put your money through the slot* at the top, it falls through and spins on the little table in the middle. When it stops spinning, it drops into the bottom. Simple enough, yeah? Quite simple and a little tacky but not particularly funny... until you see the instructions.... We bought it there and then just for the box... * heh heh i said 'slot'
