Calling the interaction an "awkward moment for the country," Maddow described the exchange as a "not-understanding-the-biology moment wherein the Justices ended up discussing the procreative capacity of dead Senator Strom Thurmond."

The judicial misunderstanding continued to the point where Maddow became so incensed that she chucked her pen across the room.
