If Rosalita had stayed bra-less and in hot pants throughout the series..
...it would still be on the air today!
Unfortunately, her over the top hot outfits got more and more demure as the series progresed. (In fact only eps 1 & 2 were noticably bra-less).
I honestly think this little something would have kept the show on long enough for the story and other non-boob elements to catch on.
