Billionaire Ty Warner (see photos of the famous product that made him rich) was lost in Santa Barbra, Calif., when he ran into Jennifer Vasilakos, a woman whose kidneys failed last year, and who was raising money to fund an expensive stem cell treatment. After she gave him directions, he gave her $50, and promised more to come. A few days later, Vasilakos got a big check in the mail (for how much?).
