Two old women driving
 

Two quite elderly women were out driving in a large car.  Neither could barely see over the dashboard. As they were cruising along, they came to an intersection. The stoplight was red, but they just went right on through.

The woman in the passenger seat thought, "I must be losing it.  I could have sworn we just went through a red light."

A few minutes later, they came to another intersection.  The light was red; and again, they went right through.
This time, the passenger was almost sure the light had been red but was also concerned that she might be seeing things. Getting nervous, she decided to pay very close attention.

At the next intersection, sure enough, the light was definitely red; and they went right through it. She turned to the other woman and yelled, "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, crap! Am I driving?"
