Google cofounder Sergey Brin once hosted a bizarre baby shower where guests wore oversized diapers and adult-sized onesies.
According to a new book by veteran tech journalist Kara Swisher, some of the most powerful people in tech and media attended the San Francisco soiree in 2008.
Swisher wrote that guests were greeted with either "a diaper with an oversized comical pin, a ruffled baby hat that came with a rattle, or adult-sized footy pajamas accessorized with a teddy bear and a sucker."
Brin was wearing a onesie as he roller-skated around the gathering, while Wendi Deng, then married to Rupert Murdoch, was wearing a diaper, according to the book.
The guest list for the event to herald the arrival of first child with Anne Wojcicki also included the then-San Francisco mayor, Gavin Newsom.
Swisher wrote that she and Newsom managed to dodge the dress code — with Newsom joking he was worried about getting photographed in the comical outfits.
Representatives for Brin did not immediately respond to a request for comment from Business Insider.
Swisher's new memoir, "Burn Book: A Tech Love Story," documents her three-decade-long career as a tech journalist. It features anecdotes about several industry veterans including Brin and fellow Google cofounder Larry Page.
Swisher wrote that she met Page and Brin through venture capitalist John Doerr, who invested $12.5 million in an early Google funding round.
Swisher recalled she'd call the pair "the twins" despite their stark differences.
Brin and Page stepped back from their respective roles as CEO and president of Alphabet in 2019 but returned to work on Google's AI efforts after the launch of Microsoft-backed ChatGPT in 2022.
Brin described himself as coming out of retirement due to AI's "exciting" trajectory. The cofounder has reportedly been directly involved in shaping Google's AI strategy and was listed in a December white paper as a "core contributor" to the company's AI model called Gemini.
