This is basically the early-80s version of a Tumblr blog, right? It took three people to write this book! And believe me, it's not because the contents belie genius brainstorming between the authors; they just wanted to get the book printed and on the shelves as quickly as possible, to strike while the fad-iron was hot.
Trust me when I say it isn't worth excerpting.
I was in high school when the Rubik's Cube hit. I wasn't into it. My friends and I loved mocking trendy junk like this; we collected, for instance, terrible/weird ET merchandise. We were, after all, hardened and cynical kids, like most born in the mid 60s. I'm pretty sure I bought this for 10¢ at Pic 'n' Save.
