The U.S. Supreme Court is an intensely private place. Cameras aren't allowed in the courtroom, and the decision-making happens behind closed doors.
Which is why it's weird when the justices come out to play with the world outside the court.
And that's one reason justices come out into the public sphere: to promote their stuff.
The other big reason is, unsurprisingly, to talk about the court. (Video via Yale University)
"You don't have to agree with Justice Ginsberg to know she does fabulous work," Justice Clarence Thomas said.
But there's a reason for the privacy, as Breyer tried to explain to Stephen Colbert on his latest outing.
"Human beings correctly and decently relate to people they see. ... Will they understand the whole story? Will they understand what we're doing? Will there be distortion? That's the argument against you," Breyer said.
Still, with the slew of high-profile cases the court heard over the past year, that privacy might be harder to come by. (Video via NBC)
