costume
Explanation
This comic is a dark humor one-liner about costume parties and political oppression.
A woman is on the phone, responding to what is presumably an invitation to a costume party. She says: "Ohh, sounds fun. I'll come dressed as a Russian political dissident."
The caption below reads: "I managed to avoid the costume party."
The joke operates on an implied dark punchline: a Russian political dissident's "costume" would involve looking beaten, poisoned, imprisoned, or dead -- referencing the well-documented pattern of Russian political dissidents being harassed, jailed, poisoned (as in the cases of Alexei Navalny and Alexander Litvinenko), or killed. The costume would be so disturbing or morbid that the other partygoers rescinded the invitation, allowing the woman to avoid the party -- which appears to have been her goal all along.
The comic works as a quick bit of gallows humor that simultaneously serves as political commentary on the treatment of dissidents in Russia, while also capturing the relatable desire to get out of social obligations.
