Police line (do not cross)

the other day my father came back from his bike-ride and said he had something for me. He then reached into his pocket and I took a step back, just to be safe. But I didn't need to worry, for out of his pocket he pulled a 'Police Line Do Not Cross' thing! It's the real deal, too. He passed some workers who where taking it down and they said he could have it. Now it has found its new home on my door.
