This conversation will hurt your brain.

QVC is not typically the go-to place for spirited discussions about the mysteries and marvels of space, but this week host Shawn Killinger and fashion designer Isaac Mizrahi turned it into one.

Killinger was presenting a "Cherry Blossom Print Boyfriend Cardigan" design by Mizrahi which she thinks looks like the Earth "when you're a bazillion miles away from the planet moon."

And from this point forward we realize our education system has failed us, at least in the science department.

"From the planet moon…" repeats Mizrahi.

"Isn't the moon a star?" she asks, questioning herself.

"No the moon is a planet darling," he says, but Killinger isn't so sure anymore.

"The sun is a star. Is the moon really a planet?" She wonders.

It goes on like this for while. They get people to Google it for them off camera, and Killinger makes a joke about having a blonde moment.

Maybe QVC can book Neil deGrasse Tyson next week to set everyone straight, and while he's at it, pitch his own line of celestial vests and ties.
