Chano and Instructions

So, I told Chano to go out and spray paint all the tee markers on the golf course the other day. I told him to use "a piece of cardboard under the rock and then spray it with the paint" You know, so the grass wouldn't get painted. Now, in my mind, that meant take a piece (ONE PIECE OF CARDBOARD) and place it under the rock, spray it, then remove the piece of card board and move on to the next rock. In Chano's head... that meant 18 pieces of cardboard under each rock. Shaking my head... My first thought was... Where the hell did he get all the cardboard from?
