Who is asked if they really "killed seven at one blow"?
Set during the Middle Ages in Europe, a king is seeking a brave warrior to kill a giant which has been terrorizing the small kingdom. There is much discussion in the village, but no one is willing to take on the task. Nearby in the same village, a young peasant tailor kills seven flies at once while at his work, and accidentally interjects several other peasants' discussion of the problems with the giant to brag loudly about his accomplishment:

Peasant (to his friends): "Say, did you ever kill a giant?"
Mickey (interjecting unwittingly): "I killed seven with one blow!"Gossip that Mickey has killed seven giants with one blow quickly spreads around the kingdom. The king summons Mickey, and asks if he really "killed seven at one blow". Mickey goes into an elaborate re-telling of how he killed the seven (flies, not giants as the king believes), which impresses the king enough to appoint Mickey "Royal High Killer of the Giant". Upon learning the misunderstanding, all of Mickey's confidence disappears and he attempts to stammer his way out of the assignment. The king offers Mickey both vast riches and the hand of his only daughter, Princess Minnie, in marriage if he can kill (or at least subdue) the giant. Smitten with the princess, Mickey proclaims that he'll "cut [the giant] down to my size", and sets off for the giant's lair.
After only a few minutes, however, he is ready to turn back and give up, but the townspeople and Minnie are counting on him. "Gosh," Mickey sighs to himself, wondering what to do. "I dunno how to catch a giant."
