Several expectant fathers are in the hospital waiting room outside the Labor and Delivery department. A nurse comes out, and announces "Mr. Jones, your wife just had twins!" "What an odd coincidence," says Mr. Jones. "I work for the Doublemint Chewing Gum company." He follows the nurse inside. A few minutes later, the same nurse returns, and announces "Mr. Smith, your wife just had triplets." "What a coincidence," says Mr. Smith. "I work for the 3M company!" He follows the nurse inside. Another of the expectant fathers starts to look worried. Soon he looks quite unwell, and is sweating profusely. One of the other men asks him what is wrong. He replies "I work for 7-UP."
