Turn of River Bridge Puns

They told me that recently they had come into ownership of a small ball of string. At first, they thought nothing of it. One day, they walked into their house and the ball of string was on the table, when they had specifically left it in a closet. They put it away again, but the next day when they came home from work, the ball was on the table again. It kept happening, and eventually it became a sort of game for my friend. They'd leave it somewhere they thought it could never come back from, and return to find it on their table.

Then it began to appear in other places.

It appeared in the middle of a company meeting. One moment, the table was empty, the next, it had a ball of string in the middle. While driving, they spotted it in the back of their car. They saw it inside of a vending machine. But at the end of every day it would return to their table.

Eventually, my friend decided enough was enough. They took the string, and threw it off a bridge into a river. As they were driving home, a car swerved and hit them, wrecking both cars. My friend staggered to check on the other driver, and all he found was a small pile of soggy string on the seat.

After that, he never saw the string again.

So after he told me this tale, I turned to him, and said, "Wow... that was quite a yarn."
