Seniors at Santa Barbara High School hired a mariachi band to trail principal John Becchio on Tuesday.
A YouTube video of the senior prank posted by the school district now has more than half a million page views.
In the video, four musicians follow Becchio down the hallways as students watch.
The band was hired for one hour and apparently Becchio didn't mind. The school district posted a photo of him with the band, and on its website said, "It was a senior prank that delighted students and staff."
This wasn't the first time Becchio fell victim to a prank. On Monday, Becchio walked into his office to find all of his things shrink-wrapped, reports The Los Angeles Times.
