SPLITS!!! OMG, I remember playing that and my opponemt ommitted to tell me he had hypermobility... Did you also play the 'chicken' one- start with legs apart and move foot in, until you were in danger of being speared by the knife? Sheath knives... those were the days... we never actually stabbed anyone, or cut them, or threatened them...
I could throw a knife at a tree and it would stick very satisfyingly, but you had to be the exact required distance for the revolution of the blade. Always held the blade, m'self.
They were indeed the days, I wasn't as keen on the chicken version; I was always tall for my age which gave me a distinct advantage in the normal splits!
