Every time I see them, I laugh. A couple of years ago, my team made a presentation to the company I worked for at the time regarding silly bands. We had a source, they were cheap, looked like fun, why not? We were looking for dollar items to sell to Michaels. They seemed perfect to us. The marketing department, with a huge lack of vision, said they were useless and could not figure out why anybody would want them. HOOT! That company is now out of business.
Just goes to show you that useless is not always useless.
