Shuffle With Care.
LMFAO can tell you that shuffling can be dangerous.
The Party Rock duo took the stage in Philadelphia but they were down a man.
SkyBlu wasn't able to attend Q102's Jingle Ball as he is recovering from a back injury.
His partner, Redfoo, described his injury as a "shuffling accident."
Not only does it zombify, shuffling and wiggling are dangerous!
