Firefly fun, with an error

I have discovered the interesting fact that all the regular male cast members on Firefly are older than all the female cast members on the program, that this span is 1,357 days, and that my birthdate lies in this gap. So, a game. Points to players who:

1. Find other shows where all the men are older than all the women (or vice versa) and the gap is smaller than 1,357 days.  IMDB and the date calculator will help.
2. Extra-super-crazy points if you find one of these gaps in which your birthdate lies.
3. Runner-up credit for finding a show where all the old cast members are older than all the young cast members.
