Has it really been ten years?

A decade ago this September, a little show called "Lost" debuted on ABC — and subsequently blew everyone's minds. It was a television series unlike any other, sparking intense online discussions, fan theories, and complex philosophies.

To honor the ten-year anniversary of the "Lost" premiere, the Paley Center for Media hosted a panel with the cast and crew Sunday night. Attending were executive producers Damon Lindelof and Carlton Cuse, as well as actors Josh Holloway, Jorge Garcia, Yunjin Kim, Ian Somerhalder, Maggie Grace, Henry Ian Cusick, and Malcolm David Kelley.

Here are 12 highlights from the warm, engaging, and sometimes smutty panel:

1. Were they dead the entire time?

"No. They were not dead the entire time," Cuse said. Happy now?!

He said that theory may have been exacerbated by the closing shot of the show. An ABC executive had suggested they include a buffer between the last scene and the commercial break, so the producers found some footage of the plane fuselage sitting on the beach. That footage incited the theories that everyone aboard had actually perished.

The characters definitely survived the plane crash and really were on a very real island. Lindelof added of the incorrect purgatory theory: "For us, one of the ongoing conversations with the audience and there was a very early perception, was that the island was purgatory and we were always out there saying, 'It's not purgatory, this is real, we're not going to Sixth Sense you.'"

But that scene of everyone in the church? Yeah, they’re all dead there.

2. When they knew "Lost" was going to be big:

Holloway recalled that he went to a supermarket after the gym, and was "sweaty and gross" (cue audience sighs). A couple of girls approached him, he said, "and were like, 'Ewww.'" That's when he knew he was famous.

3. The stuff they stole from set:

Everyone played coy, but Lindelof acknowledged that "maybe the cover of the hatch fell off a truck?" (And subsequently became his coffee table.) Cuse took the countdown clock from the hatch. Kim kept a few dresses, while Garcia still has Hurley's two paintings from the mental institution. Somerhalder cracked, "I took my dignity."

4. The beauty and difficulty of shooting in Hawaii:

Both Lindelof and Cuse praised Jack Bender, who directed many episodes and was the primary presence on set. They recounted the troubles of shooting the big raft scene — the first time, it sank, and the second time, "it was too fast... the camera boat couldn't keep up." And Vincent the dog improvised by swimming out with the raft.

5. Getting accosted by fans wanting answers:

"I had one fan I saw a few too many times," Holloway laughed. That fan offered him a "chicken dinner," which quickly became a euphemism for sex. Other panelists joked about whether he got four or six pieces and biscuits with gravy. (The phrase "chicken dinner" came up on the panel several times afterward.)

6. Dumb theories they heard or had themselves:

"I had a guy once said that when the plane was in the air, we were all cloned," Garcia said. "And the story of 'Lost' was the story of clones."
