When one thinks of a senior prank, one conjures up images of barnyard animals and lots of clean up. But the 12th graders at Eastwood High School in El Paso, TX, managed to pull a prank during their graduation that was fun for all those involved and for the school's administration.

Watch what happens after the school's principal announces the class of '12.

Dancing flash mob. Works every time.

It was also nice to see that the high school seniors of today still appreciate the musical stylings of the Pointer Sisters. Hopefully folks will still be getting their groove on to 'I'm So Excited' when the graduates' kids are high school seniors. (Can you name every song in the video?)

As for the dancing ... let's just say they have an awful lot of school spirit. Congratulations and good luck, Eastwood High Class of 2012!
