My man! Also, wow, this meme really has levels. It's based on a quote from another episode of DS9 where Worf explains that the Klingons killed their gods millennia ago
O'Brian threw hands with Worf for crossing a picket line. Not even TNG "KO'd by a blue barrel" Worf, he picked a fight with DS9 Worf, who beat Gowron in a duel.
