Greatest Mother/Groom Wedding Dance Ever! [VIDEO]

This video from a wedding has been going viral...  Heck I even saw it on CNN this morning!  Here is video of a mother/groom dance at a wedding that wound up becoming a little bit more "elaborate" than people were expecting.  I have recently learned that the mother is a dance instructor, but that doesn't make this video any less fun.  All I know is that it would be impossible for me to A.) Talk my mom into doing something like this; and B.) Have my mother be able to pull this stunt off, physically.
