Q: Funny or not: Ellen DeGeneres? A: Yes!
Q: Kathy Griffin? A: Yes!!!
Q: George Bush? A: No.
Q: Who scares you more: the President of Iran, or the President of the United States? A: They both do. All fundamentalists from any group or religion scare me. And any nationalism scares Jews by nature.
Q: Are you an observant Jew? A: Nope. I have no religion. I'm only Jewish ethnically. Culturally.
Q: Finish this sentence: I'll retire when . . .
A: Kanye West sells more albums than me."

BM: But in general, can you comment on what the difference between religious Jews and cultural Jews that seems to have come up with this Bernie Madoff issue. SS: Um, I can't imagine there's a God, personally. Um, I'm not religious. I don't have, wow. I don't have religion at all.
BM: Right on. Right on, sister. Give me a fist pump!
BM: But it's possible.
SS: I'm not ruling it OUT.
She goes on to state, "I have no religion."
