After driving for about sixteen hours, a truck driver decides to pull over and get some sleep. Just as he falls asleep, he is awakened by a knock at the cab door.
“Can you tell me the time, please?” asks a jogger. “Yes, it’s 4:30,” the trucker replies.
He falls asleep again, only to be awakened by another jogger who wants to know the time. “It’s 4:40!” shouts the trucker.
Deciding to try to get some sleep, he writes on a piece of paper: “I DON’T KNOW THE TIME” and sticks it on the windshield. But he wakes up again… “It’s 5:25!” another runner shouts at him.
