"These guys don’t give out a lot of bio info, and it was with some difficulty that I confirmed that Samberg is Jewish. Andy’s maternal grandfather, Alfred J. Marrow, served for a time as executive chair of the American Jewish Congress. While I assume Schaeffer is Jewish, I haven’t yet confirmed that. Taccone’s father, Tony Taccone, is artistic director of the Berkeley Repertory Theatre."
