Thanks to Nathan from Michigan for sending us the link to the evidence of Kronk's Jewishness. The Youtube clip is here, and the frame in question is below:
Originally, we assumed Kronk was DREAMING about being Jewish, hence the "Not a Jew" verdict. But seeing that "photo"... that changes things.
Yes, and I realize I just spent 15 minutes re-evaluating the Jewishness of a marginal fictional character. What can you do. Comes with the job. Thanks, Nathan!
