Evil Laughter

I gave Levi a sippy cup and his blankie as part of our Tues/Thurs Erin-at-school routine.  He then runs into the livingroom and jumps on my chair.  I played along and asked him if he stole my chair.  He grins and says, "Yeah."  I then said, "You are a little thief!"  He grins even bigger and gives a big dramatic "Ha HA HAAA!"
