I don't see how 2 could be left off of any red blooded American's list. We can't see how admirable her dupa is, sure, but I think there is enough there to suspect that she has a fine behind. The rest is to die for.
I can understand the criticism of 4, and I wasn't going to include her, but I felt bad that she had been left off of other lists and felt she deserved some recognition. She looks like she has some sweetness to her, and I like an underdog.
