Thor, the god of thunder, and Loki, the god of lies, habitually visit Midgard (Earth), and one evening they take refuge for the night at a lonesome farmhouse, inhabited by a couple of ordinary Viking peasants and their two children, a boy named Tjalvi and his younger sister Röskva. Thor generously offers one of his (immortal) goats which is dragging his chariot, as a feast dinner for all of them, but strongly warns any of the members of the household from breaking the bones. Loki, always treacherous, persuades the boy Tjalvi into doing exactly that, for the sake of the delicious marrow inside. Thor goes on to recount the Hymiskviða, specifically the part when he fished for the Midgard Serpent, Jörmungandr, to entertain his hosts.
