"The Pickles are a mixed Jewish-Christian family. Many fans say the Pickles are somewhat based on Klasky's real family (for example, as in the show, she is from Southern California and in real life she is a Jew and married to a Christian). There are two episodes that reflect the Pickles' Jewish heritage, one episode deals with the Passover holiday and the other with Hanukkah (in addition to episodes about Christmas, Easter, etc.). These episodes have been praised by Jewish groups and are re-run every year on Nick at the appropriate holiday times and can also be purchased on VHS or DVD."
" * In contrast to the show's tradition of dedicating episodes to explaining the story behind and meaning of Jewish holidays, every portrayal of a Christian holiday has been of a secular nature (and in the instance of Christmas, portrayed simply as a commercial endeavor; in the aforementioned Chaunakah episode, Christmas is actually portrayed as an "antagonist" holiday, as Angelica is too preoccupied with Christmas specials and the concept of presents to want to learn about Jewish heritage)."
