Well there's the obvious, so it can't be that with your devious methods. So what am I looking at? A tray of coins hanging from the boy's balls by the look of it, in piles then all over the place so he's probably moved and scattered them. I was going to say perhaps you're throwing them to see how many land on the tray, how heavy can it get, how much does he earn before he yells, that sort of thing. But seriously I need more clues here.
