Quentin Tarantino will make a cameo as himself in The Muppets' Wonderful Wizard of Oz, which will air on ABC later this season. As previously announced, pop star Ashanti will star as Dorothy and Queen Latifah will play Auntie Em. And what about a certain frog-obsessed swine? She'll play three wicked witches and Glinda, Good Witch of the North. Wow, Miss Piggy's got four roles! (I swear that was not a fat joke. I would never do that to you, Piggy.)
