The rubics cube.....
When I was in gradde school I did it under 3 minutes ONCe---but it usually took me about 5.
The ones that I liked more from Rubic's were the Pyramid---and the one called Rubic's Magic (a flat puzzle with Rings drawn on both sides).
I had a very very rare Rubic's Magic ultimate, or some shite like that-----it was silver and about twice the size of Rubic's Magic.....and hard as nuts to solve, unitl my stupid SOB little brother back then broke in to my room and tore it up to hell and back by trying to make teh folds go where he wanted.
Bastich. AT least he busted his head when he tried to run away and "slide" down the stairs when I caught him. Acually---that part makes me laugh still.....I caught him in the room, and saw his path of destruction down to my atom-bombed rubic's prize possession, and I yelled at him with a furor---he laughed and trounced out in a hurry, and was giggling cuz he had socks on and was going to slide down the stairs to get away....he was too busy laughing and his feet got under him and he did about 4 sumersaults down the stairs and landed at the bottom right on his arse.
When he landed----that was the funiest part---he looked to the left and to the right...and his eyes were like tennis balls......and his gesture was that of pure fear.....he wasn't hurt in the slightest but after the shock of landing wore off he cried and cried.
Thansk for the memory. Had to be there I know....but it sure was funny when it happened.
