Ok - this must be addressed.
I played this with some friends on Saturday night and a few things happened:
a) I am SORE
b) Even trained dancers look ridiculous playing this game
c) I miss Michael
d) This game pushed me over the edge - I'm buying a Wii.
Bah! It was SO fun! We have plans to learn an actual dance of his and perform for a church talent show. Seriously, we're ridiculous, but at least we know it.
