From the video description:
We like to have fun at our school. So, after several school closings due to snow and cold, we recorded this call to parents to see if we could make them laugh. I think we succeeded. Boone County Schools in Kentucky is one of the nation's finest. And, our awesome parents deserve this chuckle. By the way, if this video can gain us some exposure, AND you know of someone willing to help us out with some cash for technology, we DESPERATELY need it. Ellen? Rosie? Oprah? Jimmy Kimmel? We love our jobs - I hope you can tell!
