LORELAI: And the rabbit says, ‘How about that schnitzel!’
A schnitzel is a thin slice of meat that has been pounded into a flat shape using a meat tenderiser. It is usually breaded before being fried. The word is German, and means “slice” or “little slice”. Wiener schnitzel is a popular Viennese dish made of veal, traditionally garnished with a slice of lemon and served with potato salad or boiled potatoes with parsley and butter. It dates to the 19th century, and is one of the national dishes of Austria. There are numerous international versions of the dish.
The punchline to Lorelai’s alleged joke (Rory doesn’t think it is one) appears to be original.
