Crayon + Carpet = NOT good

Anyone know how to get blue crayon out of light colored carpet? I TOLD you Luke entered into the Terrible Two's. We were cleaning up this morning and I was putting toys away as was Wilson. Luke was SUPPOSED to be putting crayons in the plastic crayon tub...I look over (only about 30 seconds had passed) and he was working hard at making the carpet blue. I'd post a picture but Andy must have MY camera with him!
