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 montrer before, however, i wouldnt mind it if she was on again! i would actually l’amour to see the whole cast on the show! i'd l’amour to also see colin there, michael raymond-james and jared gilmore!
