A Filly with a Mind of Her Own

This Kentucky horse breeder had a filly that won every race in which she was
entered. But as she got older she became very temperamental. He soon found
that when he raced her in the evening, she would win handily, but when she
raced during the day she would come in dead last. He consulted the top
veterinarians and horse psychologists to no avail. He finally had to give up
because it had become ... a real night mare.
