The family deal with problems that could arise from such a situation - finding valuable furniture broken due to lousy packing and trying to set up the TV with no instructions.
Kelly and Sharon come with Ozzy to the show, but Jack stays at home, watching a documentary about marijuana instead.
While the Osbournes are still settling in, Kelly nearly sets the kitchen on fire, and Jack wanders around the background clad in pseudo Army gear in a daze.
He plays Meshuggah (whom he erroneously refers to as a "death metal [band] from Norway") on full volume to upset the neighbors.
Sharon talks with a friend over the phone saying that the original name for Ozzy's tour was going to be 'Black Christmas', but was inappropriate because of the 9/11 attacks and its aftermath, so they renamed it 'Merry Mayhem'.
On a day off, Sharon and Kelly go on a shopping spree at Saks Fifth Avenue, and loses Ozzy's credit card in the process.
Panic-stricken, Kelly takes the blame for the missing card and frantically searches her car and finally finds it under the driver's seat - in the middle of the night.
Ozzy eventually returns home and despite a broken leg, he has to fetch the cat while walking around the dangerous unfinished pool.
Kelly grows frustrated when the media continually mentions Jack's work with Epic Records, as she feels they are implying that she isn't doing anything with her life.
The Osbournes are packing their stuff at the Peninsula Hotel in New York, and Sharon tells Ozzy and Jack that one of their tour truck drivers had an accident the other day.
Later they are on a tour bus driving around New York, and Sharon is informed that Michael, their security guard, had been arrested for robbing a house behind theirs.
He plans to go out with it, but Sharon and Ozzy warns that if he goes out with an army-style haircut, a tee with 'Cocaine' on it, and holding a pocket knife, he will get arrested by the police.
The episode starts with Ozzy sitting in his dining room and enjoying dinner and recounts a time when a stray cat entered their house.
Jack then announces that Kelly has covered Madonna's "Papa Don't Preach" and that she would be singing it at the MTV Movie Awards.
The episode then ends with Jack continuing his antics with people outside his house with sprinklers as Kelly flies to New York to promote her album.
She is upset when her bag is lost (apparently seized by security because of concerns over her gun-shaped pin), leaving her without any extra underwear.
She first visits Germany, where she deals with several adoring fans and tries to fake her way through a radio interview conducted in German ("That's amazing.
When the fire finally gets going, Ozzy gives Sharon a good laugh when he tries to catch a fish in the ocean—and ends up falling on his butt.
Ozzy meets with a contractor about plans to build an outdoor kennel for all of the dogs, but Sharon quickly kills this idea.
She explains that Robert was a good friend to Aimee and Kelly after the Osbournes moved from England, so they have taken him in after his mother's death (from colon cancer).
Meanwhile, Ozzy visits the dentist and gets intoxicated from the nitrous oxide, and he appears to take the rinse water and pours it over his ear.
Robert spends a lot of time listening to music and dancing in his guest house, and Ozzy cannot get one of the songs out of his head.
The dogs are dressed in festive attire; Sharon horrifies Kelly by trying to make her dress "Christmas-y" for the family's upcoming party; Mandy Moore tries in vain to get Jack and Kelly into the holiday spirit; and Ozzy very reluctantly performs a holiday duet with fellow MTV reality star Jessica Simpson.
They apparently break up, and he returns to the U.S. Ozzy annoys Kelly when he immediately complains of boredom and says that he wants to go back to Los Angeles.
Kelly annoys everyone, particularly Sharon, with her disgusting lack of personal hygiene as she refuses to shower for a long period of time.
Ozzy and Jack are convinced that Kelly's erratic behavior and chronic illness are the result of drug use, but Sharon refuses to hear of it.
The family receives a visit from Sir Elton John, who gives Ozzy an expensive necklace that leaves him feeling a bit embarrassed; and goes on a shopping spree with Sharon, Jack and Kelly.
Feeling mistreated, Sharon clashes with her bosses to the very end, showing up late on purpose and demanding money upfront.
Dr. Phil McGraw pays a visit to the house, where he holds a frank discussion with the Osbournes about drug abuse and other issues that have affected the family's relationships with one another.
Unlike the rest of the shows from the fourth season, featuring footage shot in the previous year, this episode was taped just weeks before it aired.
