OK, maybe I am missing something here, but I don't think Samantha is all that hot. She was okay looking, but to me no better looking than Rachel.( Although maybe her doggy dress up date colored my opinion a bit! ) My opinion is that neither girl rocked his world, and Samantha being the least sincere and the most flaky, he chose her because when he dumps her, she will be less affected by it than Rachel. (If at all.)
