Get the Fat Sandwichmug. The best type of sandwich in the world.  Originated at Rutgers University by a college student looking for a late night snack.  He took a hero roll and thew basically all types of greasy foods in it (french fries, chicken fingers, mozzerella sticks, gyro meat,) along with sauces (honey mustard, mayo, ketchup, marinarra).  Comes in a large number of varities, and most have a funny name, such as the fat bitch, the fat mojo, the fat dyke, the fat night ie.  If you eat 6 of these in one sitting you get to rename the sandwich.
