does anyone know the name of that font or maybe the internet site where to download it
please help me

Well no, but I suggest going to "TVTome", (Just search Google) search for "The Golden Girls", and there should be a list of websites/fansites. Check those out and see if they have the font in their download section(s).

The font used in the Golden Girls is called Monotype Corsiva. Hope this helps.

http://www.dafont.com might have it.
