An impromptu flash mob took over Ben Franklin Elementary School as part of the school?s 50th-anniversary celebration.

Hundreds of kids and teachers sang and danced to Sister Sledge?s ?We Are Family? as part of an assembly and as members of the school say, ?It?s a true reflection of what a team and community we are here at Ben Franklin School.?

The school will also hang three new signs outside its driveway.
