In school we r in grups to perform a dance but mii grup is awful! hav u any ideas on how to make us better?!!?

I'm with Hannah on this one - embrace the badness - whatever you are doing wrong do it 'wronger' so the girl with no rythmn can justt be totally out of time and someone moving the wrong way at the wrong time will look deliberate. Choose a cheesy song that has very descriptive or story like lyrics and demonstrate them very literally - this is always good for a laugh.
