Moms have served honorably in the minivan wars, negotiated conflicting advice between husbands and fathers, and even extracted sticky sippy cups from under countless seats. Tom and Ray Magliozzi, a.k.a. Click and Clack, the Tappet Brothers, answer calls about—and from—mothers, answering questions and giving advice on cars, families, and cutting the apron strings. Their own long-suffering mother, Elizabeth, stops by to let us in on the travails of raising two time-wasting hellions and reveals that infectious laughter runs in the Magliozzi family.
