Students at Abby Kelley Foster Charter School were recently asked to film video testimonials for the Worcester, Massachusetts, school. However, unbeknown to the students, their teachers were actually planning an elaborate prank. While the students offer heartfelt speeches, the teachers are secretly dancing behind them with wild abandonment.
A soundtrack featuring Whitney Houston's "I Wanna Dance With Somebody," was later added to the video, created by Mike Penney. [Purchase the song on Amazon or iTunes.]
A few of the students seem to be holding back laughter in the videos, though it's unclear if that's because they were actually in on the prank or maybe just a little camera shy.
