My son now exclaims "COOKIE!" and crams all his food in his mouth, where he chews it with wild abandon.  He leaves about a quarter of the food in crumbs at his feet.  After a cracker incident, I spied him giggling about the mess on the floor.  He got down on his knees and 
licked the crumbs off the floor!  Then he collapsed in a fit of laugher.
