Carson is obsessed with trucks and cars. Occassionally, one of his vehicles gets a "flat tire". This simply means that it has either tipped over or was deliberately tipped over and we hear "uh oh". This is toddler for "flat tire". Carson then runs to his toy box, er, tool box, and fetches his drill to fix the flat. Neither of us have the heart to tell him that this is really an oxymoron. I keep trying to catch it on video but he gets stage fright every time I pull out the camera. So this video does have a little "coaching" but you'll get the idea.
