Sheldon too!! He loves them so much so we can't store cases of water bottles in the floor Mr. Sheldon thinks their his toy and we end up with a VERY wet floor or potatoes for that matter he loves them too.
LOL give him time Sheldon heard them crunch once when I put the case on the floor and that was all it took.
I have come to the conclusion that they are all very clever LOLOh I don't doubt it he's a damn clever bully
