Those who grew up watching Bill Nye on public TV never heard him quite like this before. The "science guy" continues to draw attention for his appearance on John Oliver's climate-themed show Sunday night, mainly because Nye dropped a number of f-bombs while making his points.

"I didn't mind explaining photosynthesis to you when you were 12, but you're adults now. This is an actual crisis, got it? Safety glasses off, motherf---ers." Typical reaction: "I just heard Bill Nye swear and it's blowing my mind," tweeted one viewer. (Read more Bill Nye stories.)
