Bill, please have Neil on more often? In fact, bring more notable scientists on the show!

[smithmcsmith]

Neil just makes me the happiest little human on Earth.

[yosemity]

Tyson's the best thing since sliced bread! Love watching him speak.

[Kaitos]

Oh my goodness...I burst out laughing when Neil grabbed Bill's finger. He gets so excited at times that you can't just help but laugh and appreciate his love for science.

[zachyoung]

I've always liked NDT's delivery. He makes really esoteric topics interesting to laymen.

[joseinteriano]

Neil is so fucking interesting. I wish he would just talk the whole show

[AWSVids]

Lol when he grabs Bill's finger! Love how enthusiastic he is!

[Skerdy]

It was going really well up until the end when Bill mentioned Carson... that "ow" and the rolled eyes from Tyson were priceless!

4:17 I absolutely love how excited he gets. His passion and enthusiasm is heartwarming and inspiring.

4:16 Tyson was so happy that someone who isn't a scientist knew some science stuff lol

[haritos]

I know this is an old video but this man (Neil) is a national treasure!

4:18 how nerdly cute are you Neil 😂👏👍💚 priceless moment

[kyleslifeofjoy]

I love Tyson. You can just tell his love for science and information. He's always so enthusiastic!

[TiggerToo]

I can't help but LOVE, LOVE, LOVE the relationship between Bill Maher and Dr. Neil deGrasse Tyson! These two guys should have their own spin-off of "Real Time." If we could add in the late Christopher Hitchens, and we've have the greatest comedic, scientific and intellectual voices and minds of our generation! YEAH, I'D PAY TO SEE THAT!

[thelionsgate]

Neil should really visit India. There are so many fans of Neil in India. He is so passionate when he explains stuff and is such an interesting personality

[dtownkid]

thousands of people just typed "water bear" on the youtube search bar...

[PrimeTimeChris]

I've heard so much about Tyson but have never actually seen any videos of him speaking or anything, and I was highly impressed. In such a short clip I understand why people love that guy so much.

[richardtaylor]

I love NGT. This man is such a nerd and is so into science. Its great.

[Crapweeds]

If the pope and Dolph Lundgren were sat in one room, and the U.S. congress were sat in another, then there would be an equal number of scientists in each room.

Bill Maher & Neil deGrasse Tyson have great chemistry and humor together and great timing!
