If you don’t know what this is, you haven’t lived.
I suggest you get yourself to Costco or Dicks or some other retailer who carries these puppies.

P.S. I hope you learn to love these, Vera. If you recall, we had them at your birthday party. You would drop them on my feet but weren’t keen on throwing or trying to catch them. Your grandma said the bruise on her leg, from one of my well-placed throws, took two weeks to disappear.
