There's these two old nuns, right? They've lived up in some mountain-top monastery over in Europe since they were little girls. They've never seen TV, or the interweb, or anything. They've never eaten anything like fast food or junk food, they just ate whatever the hell nuns eat up a mountain.

One day the Mother Superior decides to send them to New York City to help open a new church. They get there and are walking around trying to find the place when they get hungry. They see a hot dog cart on the corner and one says to the other, "Well, were in NYC now, I guess we should eat what New Yorkers eat."

The other old nun agrees, they get two hot dogs and find a bench to sit on. The first old nun opens up the foil wrapper, cringes, makes a disgusted face and throws the whole thing in to the trash can. She looks over at the other old nun and asks, "So...what part of the dog did you get?"
