Simple etiquette is listed below just as a reminder which applies to a Super Bowl Party.  Some of the etiquette listed might seem to be common sense but many times the little stuff is forgotten like greeting guests at the door.

• Greet ALL guests at the door.
• Be cheerful and pleasant at all times.
• Introduce everybody to each other even if they just "kind of" know each other.
• Keep the food and drinks coming - assign someone the task.
• Keep circulating making sure everyone is engaged.
• Have at least one planned activity like a "Guess the Ending Score Game".
• If children are coming, have kid friendly food and a kid easy activity planned.  Or pair up each kid with someone other then their parent to play a fun Super Bowl party game.
• Pay attention to your guests needs.

Have an awesome time at your party and so will your guests!   

For a unique Super Bowl party theme center everything around the numbers 43 or the Roman Numbers XLIII,  Have a cake with the numbers 43.  Party games based on the numbers and party favors.  Try having a guessing jar of small candies for a fun yummy easy game.
