Dirt Mouth

I thought I was being real slick putting a pot of dirt inside a cardboard box for Louis to play with in the kitchen while I cooked.

"Oh, if I put it in the box it will contain the mess and he'll get to play with the dirt that he keeps walking me towards out the back door and I'll buy myself some time to cook these peaches."

WRONG. Contain the dirt? I must be new.
Instead it went all over the floor as he moved it from the pot to his mouth.
