'Christmas tree' scares the daylights out of teachers

Well that's one way to spread some holiday cheer ... and fear.

As students and teachers recorded Christmas greetings at Kilgore High School in Texas, they had no idea that they were about to get pranked.

According to KLTV, the faculty thought they were recording Christmas messages and sharing memories. They had no idea that a student was hiding in the tree near them, waiting to pounce.

Though some of the teachers looked really terrified, it was all in good fun. In fact, the hilarious video was originally uploaded to YouTube by the school's media department.

We're guessing that some of those teachers will have a hard time confidently walking by Christmas trees for a few days. Can't blame them.
