Emmys sends #DCPublicSchools to head of the class

John Oliver picks up on Dave Chappelle's awards-night mention and the educational hashtag scores.

Know the old bumper sticker "If you can read this, thank a teacher"? That's what comedian Dave Chappelle did Sunday night at the 69th Primetime Emmy Awards, and John Oliver picked it up and turned it into a Twitter hashtag.

It all started when Chappelle, while presenting the best comedy director award along with Melissa McCarthy, cracked that he'd skipped rehearsal and was just going to read the teleprompter. "Shoutout to D.C. public schools," joked Chappelle, who was born, raised and educated in the DC area.

The audience laughed appreciatively, but the joke gained new life later on, when Oliver's "Last Week Tonight" won a writing Emmy.

"I would like to unexpectedly thank D.C. public schools, just to get it trending on Twitter for no reason," Oliver announced.

And so he did. Almost immediately, the hashtag #DCPublicSchools was trending nationally on Twitter, with many thanking Oliver for drawing attention to the importance of education.

And even though Sunday isn't a school day, someone from the DC Public Schools social media team was smart enough to respond.

It wasn't DC's first moment in the CBS broadcast Sunday. Former White House Press Secretary Sean Spicer surprised many by coming out with a motorized podium as part of an opening-monologue joke. (Disclosure: CBS is CNET's parent company.)
