The second night of Jerry Seinfeld's Beacon Theatre residency kicked off with a big surprise last night, with announcer declaring, "Good evening, New York City, and welcome to the 2016 Jerry Seinfeld show, please welcome Jerry's very special guest ... Mr. Steve Martin."

Vulture's Jesse David Fox recounted the experience, saying he thought the opener would be Seinfeld's good friend Tom Papa or maybe Paul Simon after seeing the guitar mic:

I lost all of my shit. This was a very special guest. In 1981, Steve Martin was the biggest stand-up in the country. He was arguably the biggest stand-up ever up until that point, regularly selling out amphitheaters when other top names were still playing clubs. And then he just stopped. He played a show and, after the show, decided not to do stand-up anymore. "My act was conceptual. Once the concept was stated, and everybody understood it, it was done," Martin wrote in his classic 2007 memoir Born Standing Up. "It was about coming to the end of the road. There was no way to live on in that persona. I had to take that fabulous luck of not being remembered as that, exclusively. You know, I didn't announce that I was stopping. I just stopped." It would be like if, 25 years from now, you realized that Kevin Hart's last tour — the one that sold out basketball arenas across the country — was really the last tour. It's the story of legends, one frequently discussed among comedians. He just stopped.

Martin told the audience, "Thank you. Jerry couldn't make it tonight... Have a safe ride home! Actually, I'm here tonight because of that old showbiz saying: Never lose a bet to Jerry."

Martin did bring his trusty banjo, and when he began strumming Seinfeld came out with an open banjo case and declared, "Okay, wrap it up."

We agree with this guy:

As for Martin, he seems preoccupied with other things today:
