Ben is annoyed to learn that both Janey and Susan are patients of another dentist...especially since Janey has a crush on this dentist. Nick uses Ben's laptop to have an 'email romance' with Isabelle - a famous model...Who's lying to who...?
At breakfast time, Nick asks Ben if he can borrow his laptop, which will allow him to start an e-mail relationship with a girl. Ben has forgotten that he is supposed to go out with Susan tonight, and has instead arranged to see a patient.
Janey tells her dad she has an appointment with another dentist, and later at the surgery Brigitte says it's a disgrace that Ben can't make time for his children.
Later Janey is admiring her teeth in the mirror while Nick makes e-mail contact with 'Isabelle'. Isabelle has told him she's a model, but Janey is sceptical.
Michael arrives home with a new pet rabbit. When the family sit down to eat, Janey tells them about Mel, her new dentist.
That night in bed, Ben tells Susan he's worried about Janey's apparent crush on Mel. But when he kisses Susan, he notices that she has had a filling repaired, and is furious when he discovers that she has also been seeing Mel. He goes downstairs and pours his heart out to the rabbit.
The next morning at breakfast, Nick brings in a photo of Isabelle - she is also in last month's copy of Vogue. They do not believe that Nick's 'email friend' is really the girl in the photo. Nick reckons the rabbit is evil.
Michael tells Ben that 'Surfing Mel' has his own website. When Susan's filling falls out, Ben, still offended, says Surfing Mel can fix his own faulty handiwork. At the surgery, Brigitte says Ben is the last to know that his wife is seeing another dentist.
That night Ben comes down and tells Nick to get off the laptop. Nick bets Ben fifty quid that Isabelle is the girl from the magazine, and says that she's coming over. Ben gets Nick to help him to find Surfing Mel's homepage, and then Susan enters to find them looking at the Oral Contacts website. Ben confesses to Susan that he was looking for Surfing Mel's website. He insults Susan by saying that Australians will have 'anything in a dress'. Ben tries to blame the rabbit for all his problems.
The next day, Susan and Ben explain to Michael that all parents argue and they are not getting a divorce. Janey arrives home from a visit to Surfing Mel. She is distraught that Mel thinks she is a child. Ben says he can probably fit her in on Monday. Isabelle arrives. She is shocked to see Nick is not a girl. She slaps him and storms away shouting in French. Nick says Ben still owes him fifty quid.
