Dance for yardage

Celebratory dances in the endzone give football charm. Plus the players get to show off their dance moves. But the problem is that without a formal place in the game such dancing is too infrequent. Also there is never any chance that the booty shaking might be abruptly stopped by the dancer being knocked down and landed on by two huge guys.

I propose that under certain circumstances a player could set down the ball and begin to dance, with yardage gained depending on total time dancing. Skilled and entertaining dancing might be worth more yards, to encourage players to practice and to discourage pro forma "dancing" which fools no-one. The dance must be ended with a tackle. I can imagine cirumstances where the player catching a kickoff (this player chosen for his dancing abilities) puts down the ball and promptly starts to dance, perhaps even with a teammate, with his blockers trying to ensure maximal dancing time. Good blocking might allow touchdowns to be scored by dance alone!
