A prankster placed a hat on Philadelphia's Girard Avenue. On the front of the hat he pinned a note that read, "Do not kick. Brick inside." Raymond Perrott, a University of Pennsylvania student, saw the hat while walking along with a friend. Reportedly, he said to his companion, "Huh, that's a joke within a joke; watch me wallop that hat." He gave the hat a strong kick, then fell to the ground, crying out in pain. The hat flew away, revealing a brick. Perrott was taken to St. Joseph's Hospital with a broken right toe. [Trenton Evening Times, Apr 2, 1915.]
