The fact that you basically have a few card tricks and no routines to go with anything you won't be ready if they moved the party back two years. If you think that all you have to do is belch and fart and they will be entertained you are sadly mistaken.
These kids have been fed the fast action of TV so when you step in and try to throw together a show you will no doubt stink the place up.
Also, if you think that any experienced kid show performer is going to give you a show they've practiced on constantly just to save your butt..think again.
You don't have a show and no one in their right mind is going to give you one. For the millionth time.. don't accept a show when you don't have one.
Get a show together and then ask for some tips..it's pretty ballsy to come on here and ask one of us to give you a show.
