i have a feeling, that miriam is actually a GIRL, and that the whole thing is a twist...like they tell the guys that miriam is a guy then they freak...then there like...just joking its really a girl. i beleive this for 3 reasons.
1- there would be MASS law suits, afterwards. and we live in australia here for gods sake, the country that gives you a defence in court if you hit a homosexual for no reason "he was threatening my masculinity".....um can you say defimation of character?
2-with most drag queens you can see the little hint of male in them once your told...with miriam you cant.
3- moral and ethics issue comes into play... which would result in bad publicity for network ten.
im thinking aloud here i could be completely wrong.
