Reese Witherspoon -- 'Bend and Snap' Class for Walmart (VIDEO)

Reese Witherspoon had Walmart shareholders eating out of the palm of her hand ... and all it took was 2 simple moves -- bend and snap!

Reese uncorked her signature move from "Legally Blonde" on Friday at Walmart's annual meeting in Arkansas, and it wasn't enough for her to do it alone. You gotta see the poor Walmart employee -- who we'll just say isn't nearly as flexible as Reese.

While Mariah Carey, Rod Stewart, Carol Burnett and Ricky Martin also attended -- we're pretty sure none of them attempted the move.

Well, most of them.
