The most difficult toy EVER! I have never been able to solve these things ever since i was i little. Theres a couple people i know that can solve it, and i find it extremely frustrating that i've tried so many times, and cant get it. Will Smith i've seen do it twice, on Fresh Prince of Bel-Air, and Pursuit of Happyness. He did it in less that a minute, so thats my goal, and if that doesnt happen, than just finishing it would be fine with me.
