I played a similar game but with bottles. they were metal and I don't know how thick, but I didn't realize they'd be that hard to knock over! Needless to say, it's the fair's game, they set the rules. Anything short of gluing them to the table is still fair game I think (no pun intended). But yup. Fair games are rip off scams and the one giant prize toy you want is better off bought online, it'll be cheaper that way.
you can't possibly expect to win a fair ground game without playing the game properly, i advise you, before you visit again, to craft some metallic spheres and cover them with green felt, when the shys owner isn't looking switch them with the regular balls and hurl those metallic nut crackers as hard as you can. now you can laugh as those concrete coconuts are disintegrated before your very eyes. for fair measure 'accidentally' throw your last ball at the man running the shy and while he's unconscious you can claim your just rewards.
If you have sex with a coconut tree without it consenting, is it rape? And if it's not because rape is a construct which does not apply to trees, then does it for animals, provided they do not actively struggle?
