What would any kind of Silicon Valley outing be Romance Archiveswithout ping pong and a heaping side of sexism?

We may never know.

Facebook CEO Mark Zuckerberg and Uber CEO Travis Kalanick both recently attended a birthday party for fellow rich white guy Dropbox CEO Drew Houston, at the Susan Sarandon-owned San Francisco outpost of SPiN. The two tech titans, one of whom is currently embroiled in a massive sexism scandal, were either unconcerned or unaware that the party was themed as a "Babes & Balls Breakfast at Tiffany's."

And if they were actually unaware, it's only because they ignored all the signs—at least one of which was a literal sign on Facebook.

The party was held less than a week before Zuckerberg announced that he and his wife, Priscilla Chan, are pregnant with a second baby girl. "We are all better people because of the the strong women in our lives—sisters, mothers and friends," he wrote on Facebook yesterday.

We imagine Mark drafted that post between rounds Friday at SPiN. Perhaps he found inspiration in all the babes? Or was it the balls? Maybe the breakfast. Either way, photos make clear that the Zuck was clearly pondering the ramifications of raising two girls in a world where women make .79 cents on the dollar. Kalanick, on the other hand, has the face of someone who keeps his eyes on the ball—just so long as that ball doesn't involve months and months of complaints about a negligent Uber HR team. Helps, too, if the ball in question is grey.

But you've gotta hand it to the two of them: Who would've thought the way to address years of reported sexism in Silicon Valley would be to literally celebrate it? Classic disruption.
