The Jonas Brothers

3 of 7
Jonas Brothers fans aren't just devoted...they're also persistent. Oprah says she's received thousands of e-mails begging her to have the band on her show.

Two fans made an impression on Oprah Show producers when they made it their mission to bring these brothers to Chicago. Kim and Alessandra, both 16, filled producers' in-boxes with e-mails, started an online petition and posted their pleas on YouTube.

"We are huge fans of the Jonas Brothers," Alessandra says on YouTube. "So we're making a video to tell you to—well, ask you to bring them on your show."

Kim and Alessandra's persistence paid off. To give them the good news, Oprah and the Jonas Brothers teamed up for the surprise of a lifetime.
