People tend to check in during these times:
Each year a twine-a-thon is held in conjunction with the annual Cawker City picnic and parade, so the ball never stops growing.
The humans consider this the largest ball of twine in existence, because they have not yet discovered Planet Twine.
It is a very big ball of twine.
I heard a lot of people have well "went to the bathroom" on it, so I would advise not touching it...
