One day Thor woke up to find that his hammer Mjøllnir was missing. In a panic Thor turned to his friend Loki, and told him about the stolen hammer. Thor suspected the giants in Jøtunheimr, so devising a plan the two then went to Freyja. They asked her if they could borrow her feather cloak in order to find Mjøllnir. Freyja, still mourning the loss of her beloved agreed, and Loki flew off in Freyjas feather cloak in search of Mjøllnir.
Minnie-ism for today:
"Give me Thor with a hammer in a dress any day!"
In Jøtunheimr, theJøtunn king Thrymr sat on a burial mound, plaiting golden collars for his female dogs. Thrymr seeing Loki asked him why Loki was traveling alone in the Jøtunheimr. Suspecting that he would get an answer, Loki told him about Thor's missing hammer. Thrymr said to Loki that he should return to the Gods with the following message, that he had hidden Mjøllnir eight leagues beneath the earth, and that it would be returned only if Freyja was brought before him to become his wife.
When Loki returned he found Thor and gave him Thrymrs message. The two then went to Freyja, and told her to dress herself in a bridal head dress, so they could drive her to Jøtunheimr and collect Mjøllnir. Freyja, indignant and angry, went into a rage, causing all of the halls of the Æsir to tremble in her anger, she refused which should not have come as any surprise.
As a result, the gods held a meeting to discuss and debate the matter. The god Heimdallr came up with a genius suggestion putting forth the idea that, in place of Freyja, Thor could be dressed as the bride, complete with jewels, women's clothing, a bridal head-dress, and the necklace Brísingamen. Thor rejected the idea, but Loki reminded him that this would be the only way to get back Mjøllnir, and pointed out that without Mjøllnir, the jøtnar would be able to invade and settle in Åsgard. The gods dressed Thor as a bride, and Loki went with Thor as his maid to Jøtunheimr.
The two disguised bandits arrive in Jøtunheimr. Thrymr commanded the jøtnar in his hall to spread straw on the benches, for Freyja had arrived to be his wife. Thrymr recounted his treasured animals and objects, stating that Freyja was all that he was missing in his wealth.
Early in the evening, the disguised Loki and Thor met in the hall with Thrymr and the assembled jøtnar. Thor ate and drank ferociously, he consumed entire animals and three casks of mead. Thrymr thought the behavior was at odds with his impression of Freyja, and Loki, sitting before Thrymr and appearing as a "very shrewd maid", made the excuse that "Freyja's" behaviour was due to the fact that she had not eaten anything for the eight days before arriving due to her eagerness. Thrymr then lifted "Freyja's" veil to kiss "her" until he caught the terrifyed eyes that stared back at him, burning with fire. Loki stated that this was because "Freyja" had not slept for eight nights in her eagerness.
The sister of the jøtnar appeared, and asked for "Freyjas" bridal gift, and then the jøtnar brought out Mjøllnir to "sanctify the bride." Thor laughed inside when he saw the hammer, he took hold of it, striked Thrymr down, and killed all of the jøtnar. Taking his mighty hammer in hand he returned home in his chariot. It was quite a site to see him as he rode back into Åsgard still dressed as Freyja and by his side Loki as his maid.
