What I know already:
When stating her name, Turanga Leela's surname comes first (her parents' names are Turanga Morris and Turanga Munda).
Some cultures put the surname last, others put it first.
What I want to know is, do we know specifically why the Turanga family puts the surname first? Has it ever been stated in an episode, or through some official channel, what culture they come from that would lead them to do this (Hungary? India?)? or is there some other reason - the mutants do this, for instance?
