Bill Nye Gets Blunt With Leaders On John Oliver's Show: ‘The Planet’s On F**king Fire!’

The science guy appeared on John Oliver's "Last Week Tonight."

John Oliver believes it's long past time to have a conversation about how to stop climate change and save the planet.

"But unless you like bad-faith conversations about farting cows, that conversation has not gone well so far," The HBO host said on Sunday's "Last Week Tonight."

Oliver noted that many on the right ― including President Donald Trump, Republican politicians and personalities at Fox News ― were "foaming at the mouth" over the issue, especially when it came to the Green New Deal, a plan backed by progressive Democrats.

So, Oliver busted open some myths about what is ― and what isn't ― in the proposal. He even recruited Bill Nye, the Science Guy, to help deliver a stirring message about the urgency of the situation.

"The planet's on fucking fire!" said Nye, who then offered up a pretty blunt demonstration.

The host couldn't hide his glee at this apparent breach in etiquette, tweeting about Nye's "entirely appropriate amount of profanity."
