New Jersey high school forced to cancel full day of classes after over-the-top senior prank: ‘Went too far’

They’ve got no class.

An over-the-top senior prank left a New Jersey high school in shambles, forcing officials to call off all classes for the day because the hijinks went “too far,” according to a report.

Pranksters at South River High School trashed classrooms and common areas on the Middlesex County campus by rearranging furniture, emptying the basketball gym of its equipment, covering hallways with toilet paper, and generally turning the school upside down, WABC reported.

“Nothing was broken. Nothing was stolen. But tables were moved, desks were moved out of classrooms, equipment was moved out of the gym,” South River Mayor Peter Guindi told the outlet.

“Listen, we were all kids at one time, I mean, we have all done our share of mischief. This kind of went too far,” Hizzoner added.

Officials were forced to close South River High School for the day over the vandalism, citing a “criminal mischief incident” — accepting the unplanned day-off after initially hoping to ring the opening bells after a 90-minute delay, WABC reported.

An investigation into the not-so-funny senior prank has been opened by the South River Police Department.

South River High School will be reopened on Friday.

The South River School District did not respond to The Post’s request for comment, including whether the students involved will face any disciplinary actions.

Other soon-to-be high school graduates in the tristate area have launched outrageous senior hijinks — with hundreds of teenagers brawling at Jones Beach State Park during a planned senior skip day last week.

Not to be one-upped, seniors at Malibu High School in California, the same week, manifested their own pandemonium by supergluing classroom doors shut and driving golf carts down staircases, causing tens of thousands of dollars in damages.
