1. Once a person knows the main rules to sandwich punch they are a player for life. Never punch a person's sandwich unless they are playing.
2. The game begins when one has first modified his or her sandwich.
3. Once said sandwich has been bitten, ripped or cut into, the sandwich is open for punching.
4. Once the sandwich is set down it must be covered with an object. Any object is welcome as long as it is an adamant object. Example: you can put a ketchup packet on the sandwich but you can't just put ketchup on top of the sandwich. Sesame seeds don't count; don't be an asshole. Other examples of objects you can use: fries, forks, spoons, knives, salt or pepper packets, napkins, wrappers, A FRIKIN OBJECT OF ANY SORT!
5. In the event that a sandwich has been bitten, ripped, or cut into by its owner and set down without an object being placed upon it, that sandwich is legally punchable. (Note: the sandwich owner must have his hands off the sandwich as well.)
6. Once punchable that sandwich is punchable until an object is placed upon it, or until it is picked up or touched by the sandwich owner.
7. The object used to cover the sandwich cannot be touched or manipulated by anyone at any time. Example: if someone bumps your table in an attempt to knock off the fry that's covering your sandwich and the fry falls off, the sandwich cannot be punched because that person has manipulated the object. There is an exception to this rule however.
8. In the event that a sandwich is unjustly punched, the person that wrongly punched the sandwich must buy the vicitim a brand new sandwich.
9. Enjoy! Welcome to the sandwich punch game. You are a player for life, and we look forward to punching your sandwich soon! We have included BYLAWS and an F.A.Q. Section for questionable senarios. Don't worry, we've got you covered!
