President and Mrs. Coolidge, visiting a government farm, were taken around on separate tours. At the chicken pens Mrs. Coolidge paused to inquire of the overseer whether the rooster copulated more than once a day. "Dozens of times," said the man. "Tell that to the president," requested Mrs. Coolidge. The president came past the pens and was told about the rooster. "Same hen every time?" he asked. "Oh, no, a different one each time." Coolidge nodded. "Tell that to Mrs. Coolidge," he said.
