Coolidge Effect: The American president Calvin Coolidge, a man of few words and less personality, was touring a chicken farm with his wife one day. The foreman noted the sexual prowess of his prize rooster. "Did you know," he said, "that a rooster can provide his services all day without stop?" "Ah," said Mrs. Coolidge, "You must tell that to my husband." Her taciturn husband turned to the foreman. "And with the same partner?" "Oh no," said the foreman, "always with different chickens." To which Coolidge replied, "You must tell that to my wife.
Thus was coined the infamous 'Coolidge Effect", which in short means that when it comes to sex, men are bird brains.
