When Bob's wife died in childbirth, he needed help with the baby. As an English professor, he couldn't really afford that. A little creative thinking solved the problem. He could offer room and board, and a little spending money, which appealed to one freshman girl. The only rub then was that they both had classes. It took two nannies to make things work. One knew a trick to get a baby to stop crying. She offered it a real nipple. If only that nipple could actually make milk. Turns out, it can.
