Little Albert came home from school with a new book under his arm. “It's a prize, mother,” he explained.
“A prize? What for, dear?”
“For natural history. Teacher asked me how many legs an ostrich1 has, and I said three.”
“But an ostrich has only two legs.”
“I know it now. But all the pupils said four, so I was the closest.”
