8. Waterpark of America
Location: Bloomington, MN
The Waterpark of America has a 10-story water slide/slide tower, making it the tallest indoor water park in the U.S. It is another park close to a massive mall, so it makes a certain amount of sense, what with the underlying logic of malls being "jam as much shit into one building as humanly possible." But the Mall of America was none to happy with the Waterpark of America. They sued them for trademark infringement, claiming that people could be confused by the similar sounding names. Really? Anyone who mixes up the two deserves to have their kids mad at them for the day.
