Thanks, Laura!
Ben, I suspect the Chenoweth "response" was the interview she had where she admonished Jeremy Piven (through the camera) to stop eating sushi and that people should know Broadway is hard work and could kick your ass if one tries it without being ready. It wasn't a response to the FISH! parody video, but it was regularly coming up as a "related video" when people watched the parody. At least i think that's what it's referring to here.
