Mark Zuckerberg shed tears, threw shade, and got (mildly) political in a commencement speech to his alma mater on Thursday.

The Facebook CEO and Harvard dropout touched on everything from income inequality to Beyonce to Donald Trump (though he danced around referring to the president by name).

Fresh off a cross-country road trip of staged meet-and-greets, the billionaire seemed genuinely excited to return to the school where he first conceived of Facebook.

The rows of ceremony higher-ups flanking Zuckerberg, whose fashion sense was dated by a century or two for the occasion, didn't escape anyone's notice.
