Teachers at Hancock High School in Mississippi went into the first day of the 2012-13 school year with what can only be described as an unconventional lesson plan.

Instead of the usual icebreaker sessions and syllabus distribution, the faculty gathered students in the gymnasium, where they performed a flash mob to Carly Rae Jepsen’s “Call Me Maybe.”

The catchy tune, which has inspired countless covers and parodies, has spent nine weeks atop the Billboard Hot 100 -- more than any other song in 2012.

This isn’t the first time this year America’s teachers have embraced their inner pop star and showed off some enviable dance moves.

In May, staff at Abby Kelley Charter School in Massachusetts asked students to participate in on-camera interviews. Unbeknownst to the interviewees, however, the teachers casually made their way into the background and photobombed the recording by dancing to what would later be Whitney Houston’s “I Wanna Dance With Somebody.”

A similar prank was orchestrated in June at Portsmouth Middle School in New Hampshire, where teachers had the opportunity to covertly bust a move behind their students’ backs when asked to reflect on the school year.
