Will Smith ripped his shirt off and rode the pony as he sang "Jump on It" in front of a huge Vegas crowd.

Will shocked everyone Friday afternoon at the Ditch Fridays ritual at The Palms.  Will was there to support his son Trey who was DJing the event with none other than Jazzy Jeff.

You gotta watch the video.  Will jumps on stage, rips his shirt off and goes crazy.  It's awesome.

And check out the video below.  The crowd was blessed with a full rendition of "Summertime."
