Kate Pistachio, definitely. She was my maid and I had an affair with her and soon had a child with her - he turned out really nice.
I really like the babies she makes - I love the jaw shape and eye colour.
I hate every single female in the Bunch family, however... Lisa Bunch is just plain ugly; hate the nose, lips and ears. Judy Bunch.. well.. ugly. Darlene Bunch, like someone said before, has awful lips.
I also don't really like Bella Bachelor. I had a child with her recently, and he turned out with massive eyes, a really pointy nose, and a really bad head shape. I thought Bella's kids would be quite pretty, but nope.
