School pranks typically involve hamburger meat and chocolate milk flying across a rowdy cafeteria. On occasion, crickets are released into classrooms.

Wednesday night, about 30 Rocky Hill High School seniors carried a 1987 Chevrolet Camaro up three flights of concrete steps and deposited the car in the school’s outdoor entryway, blocking the front doors.

“Apparently, some kids might have gotten rambunctious, end of school-type thing,” Deputy Chief William Keehner said Thursday. “At this time of year, you do see some pranks.”
