Planet Snu-Snu
So I looked that up and found this...
“The Amazonians are a race of gigantic, cavewomen like humanoids from the Planet Amazonia. They all worship the Femputer. When the Planet Express crew visits Amazonia, The Femputer sentences the men to execution by “snu-snu”, which is the Amazonian term for sexual intercourse.”
If you have to go, might as well be with a smile.
