John Lofton of the notoriously right wing Washingon Times, which is known for its appalling disregard for facts gets zinged.
Paraphrased:
Lofton: you know that there are songs advocating for incest.
Zappa: I dont think so, can you name them?
Lofton: You dont get out much do you?
then some more yammering and...
Lofton: You were in a group, The Mothers of the Invention
Zappa: The Mothers of Invention, you gotta get out more.
