A grandfather went to visit his college-age grandson at the dorm. Grandpa was astonished to find that his son was living a life of sin and corruption, as shown by the very high-heeled shoe nailed over the doorway.
"In my day," grumbled Gramps, "we would hang a horse shoe over the door for luck and then study late into the night hoping to pass our classes."
"But Grandpa," replied the grandson, "that is a whore's shoe."
