Bill Nye, the Science Guy, walks into an elevator.
He's wearing his usual bow tie. The setting is Las Vegas.
Inside the elevator are young women in bikinis, twerking and acting silly while taking a Snapchat video.
The scantily clad women see Nye, and begin to screech and scream.
"No!" "No!" "Oh my God!" the women exclaim.
"Bill Nye just walked into our elevator while I [was] Snapchatting," one of them posted.
Nye smiled and gave a little wave.
On social media, naturally, the clip went viral.
