Yeah, those are the first two to come to mind as well, but damn there are just so many! It's almost like saying what your favorite Sopranos episode is. Others so worth mentioning (and, yes, I'll be criminally leaving so many out) would be AJ's Spanish GF in the final season, the girl who was talking to Meadow's BF at the construction site (the one in the Harold & Kumar flicks), Gloria Trillo, the 'Dolly Parton' of the show herself, Charmagne, and based on not just looks but also a combo of that, her attitude, and the importance of her very character on the entire series...Adrianna!

ps - most UNDERRATED Sopranos hottie?....the one who Christopher actually ends up marrying at series' end
