Since this is about Futurama chracter names. Hmm, a probably old and well known fact, but in German (and some Skandinavian languages as well ?) there are two words spoken very similar to "Leela" and "Fry":
lila (German) = purple (look at her hair
)
frei (German) = free, independent (fits good on Fry, or?)
Anyway: Have you ever looked for the meaning of the names of the PE crew people?
Amy is origianlly Aimée or so, which means "the beloved"
Philip (Fry) is "the friend of the horses"
Turanga and Leela are from Sanaskrit origin ("game of the gods/goddesses at the creation of the world" and "running horses in the wind" or so ...)
Hubert simply means "shining mind" ... aha!
