What is the purpose of the little blue beanbag that refs in the NFL throw after a play is over?

it's purpose it to mark the end of the play and where the ball should be placed for the next play.  That location then becomes the line of scrimmage.

What does this have to do with American Football?

cause if you look like it it looks like a banner like you see people holding at footballmatches for example, they have a rectangualr peice of cloth with stuff about there team on it, in other words they are advartising there football team.

If they need more yards, they usually just let the play clock run out that cause a delay of game penalty.. that moves them back!

That is the most fun part of the game after a touch down for me. The endzone celebration. Players will pay the fine, I agree   it won't stop them from doing it.

Badminton uses a judge I think. I think Volletball does as well. Tennis may also have a judge to watch the net and serves. Not 100% on this. Football has the Refferee but also has a back judge, line judge, field judge and side judges. Each official in American football watches a different part of the field to ensure no penalties take place. They are usually very good about their jobs except during Superbowls like this last catastrophe Superbowl 40. YUCK!!!!

Hackey Sack is a game. A hackey sack is basically a bean bag, a small one that can fit almost in your hand. \n\nYou play it ONLY with your legs and feet, and the object is to just keep hitting it around with your feet, without it EVER touching the ground. \n\nYou ever seen soccer players get a soccer ball and repetedly bounce it off their feet, knees, and head without it touching the ground? Same thing.\n\nAnd when there is a group of people, you all do it together, meaning I might kick it up in the air to someone, and they hit it, it is a little circle of kids doing that.

NFL.com would proably help some. Watching is proably the best help though. Refs are actually doing a decent job now of explaining penalties, if there is anything to explain. As long as you try to wait until after the play is done your man should be happy to try to help you understand what happened. The problem with trying to explain during the play is that things are devolping so hard to explain it all as it happens. Easier to explain if there is a replay so that you know what is going to happen. Would almost be best to kinda get a tape of a game and have him explain it as it goes along. That way there is no importance to the game itself, not live so not really interrupting it.

Because intentional grounding is called when a player 'grounds' the ball to avoid a sack.\n\n\nHere's an answer to this question, posted previously:\nFor intentional grounding to be called, the quarterback has to:\n\nA. Be in the pocket,\n\nB. Be in the grasp of the defensive team, and\n\nC. Throw the ball to a place where there are obviously no receivers to catch it (with the purpose of avoiding the sack)\n\nSpiking the ball simply stops the clock before the defense has a chance to sack the quarterback. \nhttp://answers.yahoo.com/question/index?qid=20060917180454AAPQKOP

It represents sportsmanship, and respect.  It is usually more common to see in the World cup, It is a souvenir.  It is not forced to do it, it is up to the players, not all exchange jersey's at times.  It is usually done at the end of the game as to congratulate each other for their efforts.

I have always thought it to be a cheap way to end an overtime game.  I like your idea.

it can be a sending off offence if the ref sees it clearly

the random ref puller-outer-thing. I believe the refs are randomly chosen for each game
