They were obviously filming the next season of Curb Your Enthusiasm and that wasn't Moochelle, it was actually Larry David in Black Face making one of his usual inappropriate comments.
Yeah, that's the ticket.
Now that you mention Larry David, interpreting Moochelle’s gaffe reminds me of a Seinfeld episode in which George Costanza brings a deaf woman to read lips at a party and tells him “sweep with him” is “sleep with him.”
Knowing everything we know about Zero and wife, I am not sure why anyone should insist on giving them the benefit of the doubt on this.
