For most parents, parenting is hard, but for Kay, a caustic, take-no-prisoners casino pit boss, and husband Mike, a handyman and uncultivated guy's guy, parenting may as well be advanced calculus. Dealing with the demands and egos of three high-IQ children would be tricky for any parent, but it's especially hazardous for two working stiffs who barely got through high school. Mike and Kay are committed to bringing some normalcy to their kids' hectic, unconventional childhoods, but these geniuses don't make it easy.

It's 1989 and 9-year-old Sheldon Cooper has skipped four grades to start high school along with his less-intellectual older brother. As he struggles to be understood by his family, classmates and neighbors, his mother arms him with the best tool she can come up with: reminding bullies his dad is the football coach and his brother is on the team. His twin sister doesn't share his exceptional mind, but she has a much clearer vision of what life has in store for the young genius. Jim Parsons, who plays the adult version of Sheldon on "The Big Bang Theory," narrates.

Young parents Dave and Rebecca are ready to reclaim their life after years of diapers and sleepless nights.

Dave, ever the loving son, has no choice but to open the door to the people who gave him everything. But these boomerang parents aren't great with boundaries, and the question of who's parenting whom quickly becomes blurred.
