Tired of having to run to the store all the time for the kids, Bernie Mac's friends introduce him to Cost Depot. At first this solution is so simple/fun but it soon gets very addicting.

Jordan tries out for the basketball team, but the coach decides he is better suited for gymnastics -- as a ribbon dancer. Meanwhile, Wanda coaches Bryana's soccer team and turns her into a lean, mean soccer machine.

Bernie's in-laws pay the family a visit and, as usual, Bernie and Wanda's father, Lloyd, bicker continuously. Wanda asks Bernie to go easy on Lloyd this time as her parents are having money problems and cannot buy a new Cadillac. But even when Bernie offers to buy the car, Lloyd refuses because it's not the top-of-the line model he wants. Meanwhile, we learn why the two men don't get along in a series of flashbacks, as Bernie takes us back to when he met Wanda and her father didn't approve of his daughter dating a comic delivery man who told jokes on the subway.

Bernie doesn't like it that Bryanna's education consists of playing in the sandbox, tag and tiddlywinks, and he begins to question the teaching methods at the Wellington School. So Bernie volunteers as a teacher's helper for a week to see for himself. Things go wrong from the start when he demands respect from the kids and asks them to call him Mr. Mac instead of by his first name, as they do with the other adults at the school. When he gets resistance from the kids, the teachers tell Bernie that since he does not respect the Wellington way he must be on his way. He takes Bryanna with him but enrolling her in a new school isn't as easy as it seems. Meanwhile, Wanda thinks she can reason with Vanessa and Jordan and resists using violence against violence to get them to stop fighting, but she's beginning to think it's the only thing that will work.

Bernie is hoping for some peace and quiet as he prepares for a performance that night, but he must deal with the kids when Wanda's business meeting runs long.

Berine better put his money where his mouth is when he agrees to Charles Barkley's bet that he will beat Bernie's time in a 10K charity race.

Upset that Vanessa is living the free life, Bernie Mac has Vanessa work for him. Shortly, after wards Vanessa learns that his co-workers get all this free stuff because they mention they work for Bernie Mac. Vanessa takes big advantage of this, until Bernie Mac finds out. Later on, Vanessa has to bring one of his precious statues home but it breaks in a car accident. Jordan offers to fix it, with of course a price (some of the free stuff Vanessa got).

Wanda's sister visits and wants to throw a roller-disco party for Wanda's birthday.
