Enredo

When Hal and Lois go on a less-than-romantic getaway, Reese throws a party at home, which is crashed by delinquent friends of Francis, who take over the garage and hold the boys hostage.

Hal and a very pregnant Lois decide they need to get away for a long weekend. Craig takes care of Dewey for the weekend and the two bond with games and face painting. Reese is supposed to spend the weekend riding on the bus to Canada to visit Ida and back, but makes his escape through the window while it's moving and returns home to throw a party. Malcolm is supposed to stay with Stevie at his house, but also returns home for a dinner date with popular Kathy McClusky. Reese's party is quickly overrun by a gang of hoodlums led by Donnie, who set up a meth lab in the family's garage.

Meanwhile, Hal and Lois fight when it is revealed that he never got a vasectomy. This causes a separation between them during their vacation. Eventually, they make up and have sex as the room service consierge orders them out, but only gets a potty pan thrown at the other side of the door.

At the house, Malcolm and Reese enlists the help of Francis from Alaska to deal with Donnie, but it ends up in failure when it was revealed that their eldest brother has no power over his friend. Malcolm's date with Kathy, turns bad when she makes out with Donnie and joins his gang. Then after Dewey is brought home, Craig is forced to join his gang as well causing the brothers to think they're out of options to deal with them. Fortunately for Francis, Reese and Malcolm, it's Dewey to the rescue when he decides that Donnie and his buddies need a big, heavy dose of parental control. He finds a telephone and calls their mothers right away.

Sure enough, Dewey opens the makeshift meth lab by pulling on the garage door for his confrontation with Donnie and his gang of hoodlums. He immediately demands that they release Craig and leave their house right away. The gang adamantly refuses thinking it's a trick, but he remains undaunted because he reveals that he called their parents and told on them. Donnie thinks Dewey's joking, but he's in the shock of his life when he finds out that the youngest Wilkerson wasn't joking at all. Sure enough, his mother along with all the other gang members' mothers shows up at the house to give them, a piece of their minds. With the help of their mothers, he and his gang members are permanently evicted out of the Wilkerson garage with no hope of returning. Francis, Reese and Malcolm all express their gratitude towards Dewey, since his telling on Donnie and his gang of hoodlums to their mothers actually save them from risking punishment with their own parents, Hal and Lois, if they should find out what happened.

Everything in the house is back in order, Francis is back at the Grotto Ranch. Hal and Lois returns hours later, but doesn't question Malcolm's story when he mentions how well behaved he, Reese and Dewey were while they were gone in seperation.
