Seniors leave nearly 14,000 cups in school cafeteria

Seniors at Hampton-Dumont High School have left their mark - nearly 14,000 water-filled plastic cups in the cafeteria.

Custodian Terry Buss discovered the prank Monday morning.

The cups were neatly arranged. In the middle were chairs placed to read "2010," a note and $50.

Buss says the note thanked the custodians for their hard work, while the money was for the clean up, which took three hours.

Principal Trent Grundmeyer says he got a chuckle out of the prank, but then became concerned about how the students got into the building.

Fifteen students fessed up later in the day.

The prank didn't go unpunished. The school filed a police report, and the seniors must complete at least three hours of community service.
