The next episode of Charmed,titled "Hulkus Pokus" scheduled to air 11/20/05 will involve the Charmed ones turning into muscle bound "She-Hulk-like" creatures. From the promo ad it looks like they don't get much bigger in height but there seems to be some clothes ripping. For more info on the show check this link:
