To be a star or a planet? That is the question.

Or at least, it was The Question that made heads roll a few years ago and has begun to do again thanks to a revival of an old video.

Six years ago, in 2015 a QVC segment went viral after designer Isaac Mizrahi and his co-host Shawn Killinger got into a heated debate about whether the moon was a star or a planet. Little did they know that the moon, well, it’s actually just a moon.

Now, six years later, the old segment is making waves again.

Mizrahi and Killinger started the strange debate in a clip that is surfacing again on Twitter.

The clip starts out with Killinger holding up a shirt made of green, white, and blue colors before declaring, “This is what we call emerald, but really it’s more of a seafoam.” She then goes onto point out that “it almost kinda looks like what the earth looks like when you’re a bazillion miles away from the planet moon.”

Then in the familiar way that we’ve all done after realizing we might have made a mistake, Shawn mutters the phrase again, contemplating. “The planet moon.”

Not picking up on her hesitations, Isaac agrees “The planet moon.” Copping to her mistake, Shawn asks “Isn’t the moon a star?”

“The moon is a planet, darling,” Isaac replies before pulling his co-host into a sixty-two-second-long debate in which Isaac insists the moon is a planet. “The moon is such a planet I can’t even stand it,” he even declares at one point. In reaction, Shawn attempts to support her argument by going through the planets in our solar system. Unfortunately, she doesn’t get very far and names Earth, Uranus, Saturn, and “the one with the rings.”

This is when Shawn then comes to the conclusion that the Sun is a star too but Isaac quickly replies that “We don’t know what the sun is” meaning that “us” as in the whole world doesn’t know.

The whole thing is only resolved once someone off-camera confirms what most of us all already know, the moon is not a star, a planet, but a natural satellite.

Much to Shawn and Isaac’s chagrin of course.

“A natural satellite? What’s that mean? I don’t like that at all,” Shawn asks suspiciously. “A natural satellite,” Isaac replies, adding. “But things live on it. That means it’s a planet.”

Fortunately, the hosts move on with the show to sell their shirts, but fans on Twitter have yet to forget.

Someone even animated the entire sequence.
