You put your hand in the bag for a book
               and you pull out a rock
put your hand in the bag for some gum
             you pick up a stone
Your fingers clutch for cash
             and they rub against pebbles
your fingers scrabble for keys
             they grab up some gravel

You put your hand in your pocket for a rock
             and you pull out a book
put your hand in the sack for some cash
             you find it full of pebbles

Your fingers search for the stash
             they get glued up with gum
your tongue waggles for the keys
             you taste the gravel
