CNN’s Chris Cuomo probably didn’t expect Bill Nye to light up a cigarette and spit on the studio floor when he asked what could be done to prevent devastating floods like we’ve seen in Louisiana recently, but that’s basically what happened during an interview Tuesday. Cuomo wanted to talk about levees, but the Science Guy wasn’t having it.

The problem isn’t levees, Nye told Cuomo while his head spun around on his neck and smoke poured out of his nostrils, it’s climate change.

OK, he was a bit calmer than that. Watch the clip above.
