RGIII -- I'm Still Washington's #1 QB ... At The Wobble (VIDEO)

RGIII's not seeing much field time these days, but he's showing his dance moves are still in Pro Bowl form!

RGIII, along with Washington teammates Colt McCoy and Alfred Morris attended the "All-Star Survivors Celebration" earlier this week, an event in honor of 31 women currently fighting off breast cancer.

At some point in the festivities, Robert thought it would be a good idea to tempt fate ... and try to perform actual physical activity without injury.

The result? Touchdown RGIII ... not only one of the best wobbles we've ever seen (seriously, dude can move) but all for the best possible cause one can imagine.

You gotta check him out -- Hips? Check. Attitude? Check. Fun factor? Check. He absolutely slayed it.
