Don't forget the fact that despite it's just a cheeseburger, it's named "The Vonderbilt Wonder", "Halfsie Pattsies", or "Edmonton the Second". Ideally on a menu so scant on details it's hard to tell the french fries from the extra avocado.
Reminds me of that one joke from What Men Think About.
"In our restaurant, dry bread is called a crouton. It is still the same piece of slightly fried bread, but dry bread cannot cost 8 dollars, whereas a crouton can."
