i saw a report on MSNBC about the same thing. it was quite interesting, i must say. not that i want my very own crossdresser, though
anyhoo on QAF, Brian and the blonde dated in undergrad. not sure how she got preggers or why Brian was chosen. my guess is that she still has some sort of feelings for him and she picked him. this is based on some interaction i've watched between their characters. it almost seemed like the writers wanted to "straighten" out Brian and the blonde for a minute on one episode...
