I think that although she is FLOTUS, she is trying to show everyone she's human and humble. Why else would one risk exposure to possible ridicule? (Big Bro Fox News is watching!) Gotta admit that Mom dance isn't the most sophisticated thing on the planet. Cute though !

That was a real twist to have her open the last envelope at the Academy Awards from the WH ! What other FLOTUS could have pulled that off ?? Laura Bush? don't make me laugh ! (no offense to her personally , but like hubby - she always thought too highly of herself.)
