Jr.'s graduation is coming up, and he breaks the news to his family that he wants to go to college. At first shocked, Michael decides to help him make a good interview, but his anxiety and lack of good sense makes him look like a complete moron. He even tries to bride the interviewer, when he's finally asked to leave Jr. alone. The kid does reasonably good. A few days later a letter arrives at the Kyles, saying that Jr. got accepted but has to take summer school classes. Meanwhile, Clare wears a blond wig to call her parents attention, thinking she has been forgotten now that Jr. is on the spot. And Franklin applies to the soon available son spot on the Kyle family.

Junior finally graduates, and his parents give him a trip to Japan as a gift – and as a way to separate Junior and Vanessa, who are planning on moving in together and getting married as soon as they start college. Both Kady and Clare admit their sadness on Junior leaving, and Michael and Jay feel proud of having raised a semi-successful child. They go out to relive some of their memories and when they come back late at night they find Junior and Vanessa sitting in the kitchen. He's decided not to go to Japan anymore. Vanessa is pregnant.

After hearing the shocking news that their son Junior is going to become a father, Michael and Jay freak out. They try to talk with him and help him realize he can't support a family living in their garage and having no job, so Michael offers him a job at his firm. Due to Michael's teasing with the boy, he gets late for his first day and Michael fires him after his second tardiness. But seeing that his son needs all the help he can get, Michael gives him another chance. Meanwhile, Tony feels guilty about having spicy thoughts about Claire and Franklyn is still out for Junior's spot on the Kyle family.

Michael meets his friend Jimmy at the golf club and is impressed with how much hair he's grown with the help of some ""miracle"" pills called ""Come Hair Now"". As he starts to take them in overdose, weird stripes of hair rise from his chronically bald head. He's jealous of his hair and won't let anyone touch it. He also starts to get paranoiac that Jay is trying to kill him after they make a life insurance, but turns out it was just one of the side effects of the pill. Meanwhile, Kady becomes very jealous of Claire when she volunteers to be on the big sister program.

Michael wants Jr. to learn the family business by starting at the bottom, so he assigns Jr. to do menial jobs around Kyle Trucking. Jr., however, decides to use the fact that he's the boss' son to his advantage and convinces other employees to do his work for him. Meanwhile, Claire arranges a secret date with a guy she met on the Internet in a Shakespeare chat room.

When Jay works hard to get in shape and run a marathon, Michael thinks that, since he's a man, he too can run the marathon - without any real training. Meanwhile, bible-quoting Tony asks the gorgeous Claire to dress ""ugly"" so he won't feel so turned on.

When the overwhelmingly strong and gregarious Calvin, Vanessa's dad, begs Michael to give him a job at Kyle Trucking, Michael does so reluctantly and his worst fears are realized. Calvin's way of dealing with customers and merchandise leaves a little to be desired, and now Michael must find a way to get rid of the man without getting himself hurt in the process. Meanwhile, Claire gets Franklin to help her with her science paper.
