A tailor kills seven flies in one swoop, and makes himself a belt embroidered with the words “Seven in one blow.” He goes out walking and meets a giant who challenges him, having misinterpreted the phrase to mean that the tailor killed seven men in one blow. The giant squeezes a rock until it drips and the tailor does the same by squeezing a hunk of cheese. The giant throws a stone farther than the eye can see; the tailor throws a bird that flies out of sight.
This goes on until the giant invites the tailor to spend the night with them, intending to kill the guy. The tailor evades this, too, and wanders on. He finds a king who assigns him to kill two troublesome giants, which he does by tricking them into thinking one is poking the other. Enraged, they fight until they’re both dead. A couple more tasks, and the tailor gets to marry the king’s daughter. She overhears him talking in his sleep one night about sewing and mending, and she finds herself disappointed in being married a commoner. There are men sent to kill him, but he outwits them and lives on happily as fake royalty.
