I was thinking today about how I used to pass time throwing yoyos. I watched the Smother's Brothers a lot, if you know them. And just when I thought they were REALLY good, I saw some yo competitions. I learned a few tricks, and I thought I was passably good, but nowhere near these guys. I always liked the round ones, though, not the butterfly yoyo. I just didn't like the way they felt. At any rate, that's sideways from the point. Here is a video to get you started, and a podcast from the great guys Josh and Chuck, at Stuff You Should Know.
