So Matt, we do every now and then have to check in on the universe. We do. How's it doing, Neil? You know, it has issues. You know, there's a crisis, a family crisis with the galaxy. I hate it when crises happen.

We caught up with you. You're on a cruise. Man, you comedians go everywhere. You got the cushiest jobs ever.

49.492 - 66.432 Matt Kirshen

I don't know if it's cushy. It's cushy to be on a cruise, I think. Telling jokes on a cruise, that's a little more work. But yeah, we were chatting about this last time. I'm on a boat right now, and then I'm on a big land tour. I'm touring with Sarah Millican, who's a great UK comic. And then off the back of that, I'm doing some headline shows of my own in clubs. So MattKirshen.com.

You can stalk me. If you go to MattKirshen.com, you can find everywhere I am. We'll stalk you there.

70.717 - 73.12 Neil deGrasse Tyson

All right. Well, take us on a boat next time.

73.387 - 75.812 Matt Kirshen

Absolutely, absolutely. There's space in this tiny cabin.
