"The Simpsons" will broadcast a special Olympics-themed episode which sees chain-smoking Patty and her twin sister Selma racing the Winklevoss twins down the River Thames.

The popular cartoon is getting into the London 2012 Olympics spirit with a storyline based on the games in which Marge Simpson's chain-smoking twin sisters Patty and Selma are seen rowing down the River Thames against American rowers the Winklevoss twins - who competed at the 2008 Beijing Olympics.

A source told The Sun newspaper: "A rowing event at the 2012 Games transforms into a sibling-off when the dapper duo find themselves up against chain-smoking Patty and Selma."

The grouchy duo will speed past London landmarks like Big Ben and the Houses of Parliament in the race.

The episode also gives a nod to "The Social Network" with actor Arnie Hammer reprising his role as both brothers, who famously sued Facebook founder Mark Zuckerberg for $140 million, claiming he stole their ConnectU idea to create the social networking site.

The Cameron and Tyler Winklevoss characters are also seen sporting exaggerated sideburns in the style of British Olympic Gold cycling medallist, Bradley Wiggins.

The episode is aptly titled "The D'oh-cial Network" and will be broadcast in the U.K. on Sky1 at 6 p.m. Sunday.
