On this week's America's Got Talent, brother and sister duo Aaralyn and Izzy shocked judges and viewers when they ripped into their original song, "Zombie Skin," sung exactly in the style we'd imagine Carol Anne from Poltergeist would have sung it if that movie were a musical.

While older brother Izzy was wearing a skull t-shirt, 6-year-old Aaralyn dressed in a decoy outfit of pink and polka dots, surprising everyone when she belted out the first note.

They got about one minute into the song when Howard Stern stopped them, explaining, "I was afraid your voice was gonna blow out." But they made it through the to the next round, and will be headed to Vegas with the show for an encore performance, where hopefully they'll play their other single, "Lullaby Crash."
