The Winklevoss twins (born August 21, 1981) are American rowers and internet entrepreneurs, Cameron Winklevoss and Tyler Winklevoss. They competed in the men's pair rowing event at the 2008 Beijing Olympics. They are known for co-founding HarvardConnection along with Harvard classmate Divya Narendra. In 2004, the Winklevoss brothers sued Facebook founder Mark Zuckerberg for $140 million, claiming he stole their ConnectU idea to create the social networking site.

When Peter, Quagmire and Joe go to Harvard to have lunch in 'The Giggity Wife", they head to a Boston bar where they spot the Winklevoss twins. As someone starts to get an idea, one of the twins jumps in and repeats the line, claiming he said it first.

Peter brings the Winklevoss twins to Quagmire in "In Harmony's Way" while they are about to perform on Conan O'Brien's show with the intention of stealing their ideas.
