Married, with children ... As part of a health-class project, all the students at Sweet Valley Middle School are pairing up into simulated marriages.  Their assignment is to manage a make-believe household and care for an egg that represents a baby.  The only problem is, their teacher, Mr. Siegel, is picking the couples! Elizabeth Wakefield finds herself paired with snobb Bruce Patman, who refuses to help out.  Jessica Wakefield's pretend husband, Rick Hunter, teases her mercilessly and refuses to cut it out.  And Todd Wilkins gets stuck with Lila Fowler, who only wants to eat out!  Can the middle-schoolers survive two whole weeks of married life?
