Were the babies switched?
two couples had babies in the same hospital at the same time. michael and danielle had twins, a boy, michael, jr., and a girl, michelle. denise and earnest had a girl, tonja. danielle was convinced that there had been a mix-up and she had the wrong girl, since michael jr. and tonja were both light-skinned, while michelle had darker skin. danielle insisted on blood type tests for both families to check whether there had been a mix-up.
