Talk about too much time on your hands... Literally 100's of men, women, and children just completed building the world's tallest Lego tower. Using over 500,000 Lego pieces, the 120 ft. tower took over 5 days to complete and is held up by guide wires. Individual sections were put together by hand on the ground, and then placed on the tower using a couple of cranes. Check out the video after the jump.
