Many things happened at the first presidential debate Monday night. Hillary Clinton said “Woo, OK!” Donald Trump name-dropped Sidney Blumenthal, Rosie O’Donnell, and Sean Hannity—and definitely did not talk about Bill Clinton’s infidelities. But unless you watched the festivities with the sound off like a total weirdo, it was hard to miss the defining noise of the night: Donald Trump’s incessant sniffing.

Did Trump have a tiny Lego stuck up his nose? Is sniffing his nervous tick? Maybe he has pneumonia, hard to say. Anyway, enjoy this video, which is super pleasant and not at all disgusting.
