Reminds me of a story I heard from Zalman Posner. When he was a kid and learning in 770, R' Yisroel Jacobson was giving them a Chassidus class in English which was considered a novelty back then in the 40s. R' Shmuel Levitin walked by, he stopped to listen and seemed quite amused, after a minute he asked Rabbi Jacobson ווי זאגט מען אצילות אויף איינגליש? Rabbi Jacobson immediately shot back פריער זאג ווי מ'זאגט אצילות אויף אידיש.
Apologies for the Chabad lingo
