Rabbi Cartman?

Eric Cartman of South Park has (apparently) converted to Judaism and become a rabbi. Rabbi Michael Gilboa, Rabbi Esther Hugenholtz, and Rabbi Juan Mejia discuss the implications of this fictional anti-Semite's journey to Torah and mitzvot. Are there people whose past deeds are so bad that they cannot repent and convert? What does Cartman's conversion and ordination mean for the visibility and representation of converts to Judaism (and convert rabbis) in pop culture? How much of this episode will we have to take back when this all turns out to be a prank on Kyle?
