The curious thing about Madonna: The wide-open mouth indicates she's bursting with joy, but if you look carefully, she's making no expression at all. It's like there's a tiny man inside a Madonna robot who just hit the button marked "excitement."
We also asked our Facebook friends to offer up captions for this pic. Lots of you chimed in -- and lots of you mentioned Botox (quite a few folks were also outraged that we would DARE to poke fun at Madge). But the winner is Gina McNeil, who said we're not looking at Madonna at all, but "Joan Rivers II." ZING!
Thanks for playing, folks. Come back next week for more.
