There were 2 friends, a blonde and a redhead. After shopping the redhead left the keys in the ignition because she was carrying lots of things and didn't think anybody would steal it.
She hears a car going and runs out to see that her car is gone. Her blonde friend was there when it happened. The redhead asks if the blonde got their description and the blonde said she got something better. The redhead asked, "What?" The blonde said, "I got their license plate number!"
