The Valiant Little Tailor

A young tailor swats seven of the flies with one smack of his belt and is so impressed by his own bravery that he sews the words "SEVEN IN ONE STROKE" on his belt. However everyone who reads those words assumes they refer to giants not flies, which proves tricky when the king challenges the tailor to prove his might and rid the town of the pesky giants in return for half his kingdom and his daughter's hand in marriage. But the tailor is clever and manages to turn the giants on each other whilst claiming victory and the princess for himself.
