Shaq -- Wiggin' Out ... For 'Lip Sync Battle' (VIDEO)

Here's further proof Shaq will do just about anything to put a smile on your face ... donning a curly wig and doing some serious gettin' it for this week's episode of "Lip Sync Battle."

Shaq is taking on Aisha Tyler for the crown this Thursday -- and decided to recreate Jennifer Beals' iconic "Flashdance" scene for the win.

Check out the clip -- Shaq's moves are MVP worthy ... but the star of the show has to be the wig, which works as both a throwback to Beals' locks ... and a completely ridiculous piece of comedy.
