In Sunday’s episode of Last Week Tonight, John Oliver carefully and hilariously decimated Donald Trump’s odd relationship with Vladimir Putin. Fact-based as always, Oliver made it clear that while there is no direct evidence of an unconstitutional relationship between Trump and Russia, there are definitely some weird signs—namely, Trump’s constant insistence on how it would be “nice” if the U.S. had a better relationship with Russia. Oliver takes time to examine what exactly that relationship would look like. The conclusion? Putin is bad news. Watch the segment unfold in the clip above, and watch till the end when Oliver enlists a dance troupe to sing the message to Trump, complete with a bouncy Putin head to guide you through the lyrics.
