True story:
My Dad was a terrible tease, he never knew when ENOUGH WAS ENOUGH! One day in the late 40s or early 50s, he was home from work (which was rare, he worked 90-hour weeks) and feeling frisky. Mom was knitting, and he kept poking and tickling her, and pulling at the yarn. She warned him about eight times not to do it again.
He did it again.
Mom took a pretend swipe at him with one of the knitting needles and connected: pierced all the way through the meaty part of his upper arm. Dad was blood-phobic and fainted dead away. Mom poured cold water on him until he came to, drove him to the family doctor, who cleaned up the wound as best he could and sent them home with some nasty "poultice" stuff that Mom had to apply several times a day for weeks. It must have worked, because eventually Dad's arm healed.
He never teased Mom again while she was knitting.
