Giosué Orefice: "No Jews or Dogs Allowed." Why do all the shops say, "No Jews Allowed"?
Guido: Oh, that. "Not Allowed" signs are the latest trend! The other day, I was in a shop with my friend the kangaroo, but their sign said, "No Kangaroos Allowed," and I said to my friend, "Well, what can I do? They don't allow kangaroos."
Giosué Orefice: Why doesn't our shop have a "Not Allowed" sign?
Guido: Well, tomorrow, we'll put one up. We won't let in anything we don't like. What don't you like?
Giosué Orefice: Spiders.
Guido: Good. I don't like Visigoths. Tomorrow, we'll get sign: "No Spiders or Visigoths Allowed."
