''Fortysomething'' is a {{Britcom}} starring Creator/HughLaurie as Paul Slippery, a London general practitioner who begins to suspect that he's hearing other people's thoughts -- most notably those of his wife, Estelle. But when you consider that Estelle has started working for an ambiguously flirtatious power lesbian, Paul's eldest son (Creator/BenedictCumberbatch) is bent on revenge against his middle son for stealing his girlfriend (whilst involved with her sister!), Paul's youngest son is using the family home as a base for various entrepreneurial activities, his colleague (Creator/PeterCapaldi) is completely bonkers, and he can't even make an intimate dinner for his wife without his entire family asking for a taste of "Proud Banana"... well, it's not completely unreasonable that Paul would go a little mad.

The show ran for one six-episode series on {{ITV}} in 2003 and was released on DVD in the summer of 2008, at which point it was known in America as "that TV show where Series/{{House}} plays a ''nice'' doctor". Since the fall of 2010, it has become known as "that TV show where Series/{{House}} is Series/{{Sherlock}}'s dad", and from 2013 onwards as "that TV show where House and Sherlock have a ham-off with [[Series/DoctorWho the Twelfth Doctor]]".

Not to be confused with the late '80s/early '90s ABC show ''Series/{{Thirtysomething}}''.
!! This show provides examples of:
* AllMenArePerverts: All three of the Slippery brothers, and even Paul on a couple occasions.
* DawsonCasting: Creator/BenedictCumberbatch was about six or seven years older than university student Rory; sixteen-year-old Edwin was played by twenty-year-old Joe Van Moyland.
* EveryEpisodeEnding: Each episode ended with Paul and Estelle going to bed at night.
* HearingVoices: Probably Paul's imagination, but it's never conclusively settled.
* TheImmodestOrgasm: When Daniel and Laura become official, they celebrate by having sex. ''Very'' loudly. With Paul and Rory still around no less.
* JerkAss: Daniel. Dr. Pilfrey as well.
* AMindIsATerribleThingToRead: The thoughts Paul thinks (maybe) he hears from Estelle are... not flattering.
* MistakenForCheating: Paul was initially afraid that Estelle was actually a closeted lesbian when hearing of her encounter with a "nice lady in the park." He also gets especially incensed at the thought of Dr. Pilfrey's constant attempts to woo Estelle.
* NiceGuy: Rory
** NotSoAboveItAll: He does have his moments of letting his jealousy get the better of him, especially when he plans revenge against Daniel.
* OncePerEpisode: Each episode takes place in a single day, beginning with Paul and Estelle waking up in the morning and ending with them going to bed.
* OpeningNarration: The first line of every episode is "This... is Paul Slippery."
* RunningGag: Someone will ask Edwin why he's not at school.
* SiblingTriangle: More like sibling ''rectangle'', which eventually resolves itself into something approximating DoubleInLawMarriage.
* YoungEntrepreneur: Edwin, much to Paul's chagrin, as one of Edwin's business ventures results in a load of refrigerators delivered to their house... and another results in crates of sex toys sitting around the Slipperys' yard.
