Remember when kids clothespinned baseball cards into the spokes of their bikes to make it sound like a dirtbike?

ROTFLMAO! I forgot about that! I used to do that!

I'm extremely amused by Turbospoke, although I confess the concept loses some of its charm when there's a DEVICE on the market to do it. I like the homespun clothespin-and-baseball-card idea better. ;)
