Context: Navalny called a member of the FSB poison team posing as one of his superiors, and duped him into divulging that a follow-up FSB job included washing Navalny's seized underpants of possible traces of the Novichok poison that was used in the assassination attempt.

"We all remember Alexander the Liberator [Alexander II] and Yaroslav the Wise [Yaroslav I]. Well, now we’ll have Vladimir the Underpants Poisoner."
