One of the biggest splashes at South by Southwest on Saturday was when Bill Nye (yes, "The Science Guy") made a surprise appearance at a session featuring Democratic congresswoman Alexandria Ocasio-Cortez that drew overflow crowds. He even had AOC chanting "Bill, Bill, Bill" at one point.

But did you know that long before he became a nationwide TV sensation, Nye was locally famous in Seattle as Speed Walker?

 

In the early 1990s, Nye was a cast member of "Almost Live," a half-hour locally-produced comedy show that aired before "Saturday Night Live" on Seattle's NBC affiliate. "Bill Nye the Science Guy" started on that show.

But Nye also did other skits, most memorably as Jeff Bimmel, a mild-mannered reporter who could instantly transform into "the physically fit superhero who fights crime while maintaining strict adherence to the regulations of the International Speed Walking Association! Heel-toe, heel-toe!"

After Saturday's session, Nye posted a photo of himself and Ocasio-Cortez, with a brief message that concluded, "We can address climate change, if we get together and get to work."

Nye was part of a panel about space exploration earlier Saturday at SXSW. Nye made several appearances at SXSW in 2017.
