In the Boston, MA suburb of Hingham, MA, outgoing and retiring Hingham Middle School principal, Roger Boddie, was surprised by his staff and students by putting together a flash dance mob.

Principal Boddie thought he was being interviewed on the progress of the schools' expansion project. He was showing off the new construction and talking about the new auditorium that is being constructed and he was eventually led up to the roof where he saw the entire student body on the parking lot and was wondering what was happening. Then he realizes what is happening and seemed pretty touched by what was pulled off without him knowing.
