"Kif Gets Knocked Up a Notch" is the first episode in season four of the American animated television series Futurama. It first aired on the Fox network in the United States on January 12, 2003. The episode was written by Bill Odenkirk and directed by Wes Archer. The plot centers on Kif and Amy's relationship; Kif is suddenly impregnated so he returns to his homeworld to give birth. The episode was generally well received by critics.

Amy is unhappy with her long-distance relationship with Kif and wants to see him in person again. When the crew is sent to deliver a giant pill to a planet near where Kif is stationed, Amy stows away on board the Planet Express Ship. While the crew is asleep, Amy changes course to meet with Kif. When Zapp Brannigan sees the ship, the Planet Express crew joins him on the Nimbus. On the Nimbus, Kif implores Amy to move in with him and shows her the HoloShed to illustrate what life would be like with him. Soon, however, the shed malfunctions and the holograms that invade become real. When the holograms reach the rest of the crew, Zapp Brannigan accidentally blasts a hole in the ship, which sucks out the holograms. Everyone else on the ship is also sucked towards the hole, but they hang on to each other's hands until the moon from the Holoshed plugs the hole. Later, at the sickbay, the doctor reports that everyone survived with only minor injuries, and also reveals that Kif is pregnant.

Kif explains to the crew that his race reproduces through touch, their skin being a semi-permeable membrane which can absorb genetic material. They become sexually fertile whenever they experience strong positive emotions for another being, as Kif did with Amy on the HoloShed. Fry points out that everyone on the ship touched Kif while he was trying to hang onto them to prevent being sucked through the hole and it is unclear who the mother is. Professor Farnsworth uses an invention of his, the Maternifuge, to determine the real mother. The machine filters out its occupants based on a DNA sample, revealing that the mother is Leela. Amy is instead only the "smizmar" of Kif's children, which nevertheless makes her the "real" mother by Kif's standards.
