This is power.

HBO's "Last Week Tonight With John Oliver" won Outstanding Writing for a Variety Series at the 2017 Emmy Awards. In his speech, John Oliver referenced presenter Dave Chappelle's quip from earlier in the night, thanking DC public schools.

Oliver said he too wanted to thank DC public schools, just to get that trending for no real reason. So he asked fans at home to tweet #DCPublicSchools.

And they did.

Pretty much immediately, #DCPublicSchools got itself trending in the U.S.

Between the two of them, Dave Chappelle and John Oliver could get fans to tweet or do anything, and that was the chosen topic of the night. But every Sunday night, Oliver gets fans tweeting and talking about even more serious issues -- in his own cheeky way -- and that's why he keeps winning.

Here's the full list of winners at the 69th Annual Primetime Emmy Awards.
