There's nothing funnier than watching 300-pound linemen "Just Dance."

Joe Staley, Alex Boone and Mike Iupati might be getting ready for the biggest game of their professional careers right now, but they took some time out of their busy schedules to have a dance off to the popular video game, "Just Dance 4."

All three men are part of the starting offense for the San Francisco 49ers, and watching them move with such agility, we might see more of these videos from other offensive linemen next season.

It's really amusing to watch these tough guys dance around like little kids, grinning from ear to ear while they try to outdo one another.

Whatever you may think about their performances, it's refreshing to see football players who know how to party without getting into trouble. 

49ers fans just hope these guys will still be dancing after Super Bowl XLVII on February 3, 2013.
