Riddle: Two girls enter an ice cream parlor. The year is 1904. They start walking toward the counter to order. The first thing they see is a man lying unconcious on the floor, with water and glass all around him.
Answer: The man went to change the lightbulb above the counter. He used the big ice cube from the ice box to stand on. He fell off the ice cube with a bulb in his hand. The bulb shattered on the ground and the ice cube had melted by the time the girls got there.
