In the interest of National Security I received a call today about a suspicious looking green substance that was under my couch. Honest to God, I did move my couch and clean under it a few weeks ago when we put the Christmas tree in. I know I'm bad because I only clean under my couch a few times a year but Holy Mother of God - where does this stuff come from? Can 2 cats and 1 dog make that much dust in three weeks? I guess the answer is yes. I didn't know we had gumballs in the house.
