Simon keeps on truckin'.

I caught Simon pushing the toy dump truck across the living room.  Then he crashed it into the coffee table, where he decided that the cargo was more valuable and "stole" it.  
Actually, this is the first time I've seen him make the truck go forward (usually he's either biting at the front end while chasing it or swatting it with his front paws to make it move).  Our little guy is learning!
