A Quick Anecdote

I was checking out the new Oriental Trading Company Halloween catalog looking for ideas for "Boo-ing" treats (more on Boo-ing later) and I came across what I believe to be a hilarious customer testimonial on these items:

They are the ever popular Glow-In-The-Dark Bouncing Eyeball. 
And an OTC customer had this to say: "These bouncing eyeballs are so useful." And then they go on to tell about putting them in a skull, their bookcase and even floating them in their punch.
While I may find them cool, and maybe even describe them as handy for Halloween decorating how can anyone say a glow-in-the-dark bouncing eyeball is useful!?!?
Seam ripper while I am sewing = useful
Clorox Wipes for quick bathroom cleanup = useful
Even a long sleeve sweatshirt when you have a runny nose = useful
But a glow-in-the-dark bouncing eyeball!?!?
