When Mika Brzezinski was tasked with reporting on the chlorine attack at a Chicago furry convention this weekend, the confusion in her voice became palpable. “Did I get that wrong?” she asks, stumbling over the words “furry convention.” No, Mika. No, you did not.

While their co-host tries to continue reporting on the story with a straight face, Joe Scarborough giggles helplessly into his fist and Brzezinski hides her face. During a cutaway to news footage of the story, the two hosts apparently filled Mika in on what a furry is, and she straight up runs out of the studio.

Sorry, Mika. Some things you can never unlearn.
