Plot
Amy has been receiving phone calls for a year, where the caller stammers and then hangs up. The calls are from Kif, who is in love with Amy but is too nervous to speak. Zapp realizes that Amy and Leela know each other, and asks the two of them to go on a double date with him and Kif. Leela agrees as a favor to Amy, and they go to a restaurant aboard a space liner.
Kif uses Zapp's characteristically boorish pick-up lines, offending Amy. To prevent her and Leela from leaving, Kif sings karaoke. Amy is touched by this, but Zapp pushes Kif off the stage and sings to Leela, causing the passengers and crew of the ship to flee the restaurant in terror. Zapp crashes the ship into the planet Amazonia, where the Amazonians, a race of giant, muscular, tribal women, capture them.
Fry and Bender travel to Amazonia to rescue their friends but are also captured. They are taken to the Amazonians' leader, observing Amazonian society along the way. Fry, Zapp, and Bender ridicule female values, which makes Leela and Amy appreciate how good life would be without men. When the Amazonians ask what the purpose of men is, Amy explains, and the Amazonians realize that what she is describing is "snu-snu" (sexual intercourse), something they have heard of but never experienced.
