"At oral argument, Justice Elena Kagan, one of the court's best questioners, sometimes... just shuts down... Still, her anger is often palpable, the color literally draining from her face. "

"And Justice Stephen Breyer on occasion just holds his head.... There isn't a lot of love lost among the court's six conservatives either.... If you watch carefully, you can see conservative eyes rolling from time to time.... [M]any of the conservatives are vying for the position of intellectual leader of the conservative majority, while the chief justice privately worries about going too far too fast. There are, in addition, some long and perhaps not so buried resentments among the conservatives. Alito on occasion barely conceals his disdain for Roberts.... In recent decades, the court has built its legitimacy on a certain degree of moderation — giving the left some of what it wanted and the right some of what it wanted. The left got gay rights and gay marriage, and some limits on presidential power exercised in the name of national security. And the right got expanded religious liberty and expanded free speech, which brought with it expanded corporate spending in elections.... But... the court's conservatives detest each other in the same way that the justices did in the 1940s. Back then, they couldn't agree on anything because, as [Noah] Feldman notes, 'they hated each other.' and even though they might have been able to to reach a consensus, they didn't 'because the hatred was so deep.' To cite just one example of how bad it was, Justice Felix Frankfurter called Justice William O. Douglas 'one of the completely evil men I have ever met.' And Douglas referred to the Austrian-born Frankfurter, who was Jewish, as 'Der Führer' and that was during World War ll."

Writes Nina Totenberg in "Supreme Court justices aren't 'scorpions,' but not happy campers either" (NPR). 

The "scorpion" quote refers to "9 scorpions in a bottle," a famous phrase that Totenberg doesn't give a source, perhaps because it's so famous, but perhaps because the usual attribution — to Oliver Wendell Holmes Jr. — seems incorrect. Noah Feldman's book "Scorpions: The Battles and Triumphs of FDR's Great Supreme Court Justices Paperback" begins with the quote "The Supreme Court is nine scorpions in a bottle," attributed to Alexander Bickel, law clerk to Justice Felix Frankfurter, 1952–53, and drops this footnote:
