Captain Guy Lucas, who judged hunters in the first half of the 20th century, finished judging a class and left the ring. He was accosted by a peeress, cross because her hunter had not been placed. "You," she told Captain Lucas, "should be judging cows, not horses!"
"Yes ma'am," said Captain Lucas. "And if I had you in front of me I should give you the first prize!"
