SPOKANE, WA (CNN/KREM) -- A prankster, or pranksters in Washington state have a little too much time on their hands.
Someone stacked a park's picnic tables into the shape of a pyramid in Spokane. They also put construction lights at the very top.
This is the fourth time in recent weeks officials have had to deal with the so-called "table stacker." They say they don't know if the stacker is an average vandal or trying to express art.
One person says, "I think it looks kind of nice. It's interesting. Again, I just don't know about the -- the lights up on top." Another says, "As cool as it is, it's upsetting because it takes money away from the city, and we're already on a budget. It takes time away from people who have to do their job."
Parks officials say it takes a lot of resources to undo these tables, using a forklift and a bucket truck.
They also say this stacking is dangerous because the tables could topple over and hurt someone.
