how can i start a petition to get lana parrilla, josh dallas and ginnifer goodwin on the ellen show?

i really really wanna see them on that show! jennifer morrison was already on the tunjuk before, however, i wouldnt mind it if she was on again! i would actually Cinta to see the whole cast on the show! i'd Cinta to also see colin there, michael raymond-james and jared gilmore!
