• My dog plays invisible Frisbee.
    He catches invisible balls.
    He rides an invisible skateboard.
    He hurdles invisible walls.

    My dog has perfected the practice
    of doing invisible tricks.
    He jumps with invisible jumpropes
    and fetches invisible sticks.

    He barks at invisible mailmen.
    He growls at invisible cats.
    He'll bring me invisible slippers
    and even invisible hats.

    He chases invisible squirrels
    whenever we go for a jog.
    He's clearly the greatest dog ever.
    I love my invisible dog.
