Hjalmarr's insult and the birth of Kveld and Elding

Hjalmarr's horses have all been exhausted by his ceaseless questing, and so he demands that his sister Oddruun breed him a stronger steed. Frustrated, she asks why, if he wants a new horse so bad, he doesn't breed one himself. Hjalmarr pridefully remarks that breeding and feeding animals is woman's work as part of maintaining the household, and that he had better things to do. Oddruun was furious at this dismissal by her rude brother, and began to form a plan to get back at Hjalmarr for this insult.
"Better things to do" as it turns out, was drinking with Jack Daniels in The Crowded Hearth. Oddruun captured the strongest male Sleipnir in the seven seas, and persuaded him to come to The Crowded Hearth with her with promises that his offspring would be forever cared for by the gods. Oddruun then entered The Crowded Hearth and told Hjalmarr that she had found a godly horse in the care of a fair maiden who was coming to The Crowded Hearth, and that the maiden would give him her grand steed in person. Oddruun offers many toasts to Hjalmarr's new steed and his bravery and glory, and once he is so drunk that he can scarcely stand up straight he heads to his bedchambers at The Fair Friend's inn. Oddruun then retrieves the Sleipnir, disguises it in a dress and wig, and sends it into Hjalmarr's rooms. Hjalmarr drunkenly demands to know who it is who disturbs him, and Oddruun, using magic to speak through the Sleipnir's mouth with a different voice, says that she is the maiden who has come to deliver a fine steed to the glorious god of battle on the condition that he make love to her. What follows is a humorous account of how Hjalmarr is impregnated by the Sleipnir, and retellings often include the storyteller's own unique jokes about the lewd misunderstandings that ensue, such as Hjalmarr complementing the Sleipnir's beautiful hair, being confused by the maiden's many legs, and being fooled into thinking that the Sleipnir's penis is a mast, suppository, or magical totem that gives men pleasure.
After recovering from his hangover, Hjalmarr is confused and alarmed by his newfound pregnancy, and his mother Ragnhildr advises that instead of seeking out his sister to deliver vengeance for being made a fool of, he should seek out the great and wise giantess Ama who might act as his midwife and wetnurse for a price. Hjalmarr travels to the home of Ama, becoming ripely pregnant on the journey. Meanwhile Ragnhildr corners Oddruun, reproaching her for her trickery and ordering her to aid her brother in recompense. The giantess agrees to help Hjalmarr but demands that he keep her house and perform her chores as payment for the duration of his stay. Hjalmarr proceeds to be given a series of titanic tasks of "woman's work" such as weaving Ama a new gigantic dress before sundown, feeding 10,000 giant chickens and goats, and sweeping an entire mountainside. Hjalmarr struggles mightily at these tasks, often succeeding only due to the timely (and hidden) intervention of Oddruun.
Eventually his water breaks and as promised, Ama helps him to deliver his children. All the while Hjalmarr, exhausted and irritable, cries out that we would rather leap into the jaws of a bear or be run through with a spear than endure the pain of childbirth. He declares that no warrior on the field of any battle has ever endured an injury as painful as giving birth, and the hidden Oddruun tries to refrain from giving herself away by laughing. He gives birth to twin Sleipnir, large and strong, with shining coats, and names them Kveld and Elding. While Ama nurses the children on her breast, Hjalmarr must complete more tasks, such as cleaning up the mountains of manure produced by his sons, repairing the holes in Ama's home created by their carousing, and devising clever ways to make them sleep restfully each night.
Once his sons and steeds outgrow Ama's milk, Hjalmarr returns home to be met with a baby shower from his fellow gods. He recieves many gifts, but none so grand as those given to him by Oddruun and Ragnhildr: 16 magical horseshoes for his sons allowing them to gallop across the water, and a new ship, fitted not with a mast and sails but with reins and bridle. At the end of the party, Oddruun pointedly makes a comment about how Hjalmarr should avoid silly things such as "women's work". Hjalmarr, oblivious to the irony, loudly reproaches her for speaking ill of such work, and proudly declares that any man who derides the feminine arts as lesser is a fool indeed.
