A blonde gets lost in her car in a snowstorm. She remembers her father's advice, "If you ever get stuck in a snowstorm, wait for a snow plow and follow it." Soon a snow plow comes by, and she follows it for about 45 minutes.
Finally, the driver of the truck gets out and asks her what she is doing. She explains the advice her father had given her. The driver says, "Well, I'm done with the parking lot here at the mall, now you can follow me over to the bank."
