Midge is waiting for a limousine to pick her up. Tonight she is making a guest appearance at the country western festival and she doesn't want to be late. She has rehearsed her new songs for the past two weeks, and tonight is her big night! Just as the limo arrives, Midge's phone rings.

Midge smiles and says, "Thanks, Barbie. You're the best friend ever!"
