I can remember
In the final days of my high school career seeing a kid that had read a book about Rubiks Cube solving one behind his back. It took him about a minute I guess, and when he was done even he was impressed. Me, the only way I've ever "solved" a Rubik's Cube was to peel the stickers off it, and stick them back on. The cheap knock offs had stickers on them. Damned maddening puzzle from my perspective.
