Bill appeared on Dancing with the Stars. The entire theater was giving him a standing ovation after his dance, all chanting "BILL! BILL! BILL! BILL! BILL!" After almost 15 years, his fans still love and remember him!
After every performance he made. Especially after he was immobilized from a knee injury. The man was advised by his doctor to stop dancing but Bill freaking Nye decided to devise a knee brace that effectively rendered him a peg leg. Instead of letting that stop him, the man dressed up as a cyborg and incorporated that into his dance. He didn't win, but as previously mentioned, the audience reaction was huge.
Similarly, around ten years after the show ended, Nye started doing speaking tours at colleges. It's not at all uncommon for the tickets for his lectures to sell out within minutes. As was once overheard standing in line for said tickets, "Dude's a rock star!"
Along with that, Nye gets a whole load of bonus points:
Crushing Ham in his own "museum" (which teaches that which is demonstrably false as it if it were factual)
Utterly DESTROYING Ham hard enough to get other Creationists to say that Nye had won.
And also capsizing the myth that the story of Noah's Ark in the Bible actually happened.
And making sure Ham's attempt to gain publicity for creationism backfired.
To put this in perspective, scientists have refused to debate creationists for years for a few reasons. First, it lends legitimacy to the idea that there even is a debate. Second, creationists often use dishonest debate tactics that can frustrate people who are unprepared for them while seeming legitimate to people who don't know better. Some people worried Nye would be tripped up by common creationist debate tactics designed to be repeated rapid-fire so an opponent doesn't have time to counter them all (commonly called the "Gish Gallop" after creationist Duane Gish, who specialized in the technique). The well-known script gave Nye plenty to study and work around.
The incident left Ham's ego so badly bruised that, over a year later, he's still trying to counter Nye's arguments, leaving him a laughingstock in the creationist community. Bill Nye demolished Ken Ham.
Teaching kids how to make a fire extinguisher out of ridiculously common kitchen materials in the chemical reactions episode. There's a good chance that somewhere out there, that saved somebody's life.
The fact this fellow started out as a Boeing engineer, not a trained scientist, actor, or entertainer. He had a side venture doing stand-up, which got John Keister's attention. Keister was impressed enough to lobby KING-5 to hire the guy for Almost Live!, and Nye became their stand-out performer.
