The picture of Erin in the paper shows her with her right arm bent. But when the picture was taken, her arm was straight.
Ben tells Erin at least the paper didn't print her name with the picture. Somehow everyone knows not only who Erin is, but her address to send her fan mail and are able to call her on the phone as well.
When John walks in the girls' room while Erin is practicing her speech, the shadow of the boom mic is visible on the wall in the top right corner of the screen.
When the phone rings while John is yelling at Ben and Erin about the picture, he says hello before the handset is by his head.
