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."
