Fairly easy. Bang Britney, she's a little psycho but that's not a bad thing for the one-nighter. Kill Paris, she's extra annoying and I'm not all that fond of the super skinny chicks anyway. Marry Christina, she's the only one left over but, of the three, that seems like a no-brainer anyway. And, for the record, I'm against killing chicks in general.
