Yeah if you look under complete rules, it has a list of Disney 'Stars' that may sign it. If I won, I would tell them I don't want any of these people near my machine.
"The following Disney Channel & XD stars may sign the arcade console: Stefanie Scott - Ant Farm, Peyton List – Jessie, Kelli Berglund - Lab Rats, Roshon Fegan - Shake It Up, Ross Lynch - Austin & Ally, Dylan Riley Snyder - Kickin' It, Zendaya - Shake It Up, Calum Worthy - Austin & Ally, Tyrel Jackson Williams - Lab Rats, Bradley Steven Perry - Good Luck Charlie, Caroline Sunshine - Shake It Up, Jason Dolley - Good Luck Charlie, Karan Brar – Jessie, Adam Irigoyen - Shake It Up, Cameron Boyce – Jessie, Billy Unger - Lab Rats, Bella Thorne - Shake It Up, Raini Rodriguez - Austin & Ally, China Anne McClain - Ant Farm, Sierra McCormick - Ant Farm, Mia Talerico - Good Luck Charlie, or Spencer Boldman - Lab Rats."
I've never heard of one single person on that list lol, let alone the show.
