Two elderly women were out for a Sunday drive in a large car and both could barely see over the dashboard. As they were cruising along, they came to an intersection.
The stoplight was red but they just went on through. The woman in the
passenger seat thought to herself "I must be losing it, I could have sworn we
just went through a red light".
After a few more minutes they came to another intersection and the light was red
again, and again they went right through.
This time the woman in the passenger seat was almost sure that the light had
been red but was really concerned that she was losing it. She was getting
nervous and decided to pay very close attention to the road and the next
intersection to see what was going on.
At the next intersection, sure enough, the light was definitely red and they
went right through, and she turned to the other woman and said, "Mildred! Did
you know we just ran through three red lights in a row? You could have killed
us!"
Mildred turned to her and said "Oh, am I driving?"
