BOTHELL, Wash. -- Bothell High School students made a lip dub music video to show support for one of their teachers who was attacked on campus last week.

The high-energy production features hundreds of students and teachers waving “Bothell Strong” signs while dancing and lip-syncing to songs as a camera follows them through their school.

“It has brought us together and made us stronger,” said Hannah Merrill, a senior who directed the video.

Cal Pygott, 63, a woodshop teacher, is recovering at home after he was assaulted in a classroom. He told police he was working on a loud machine when someone hit him from behind, knocking him out. Pygott was found stumbling in a hallway with a zip tie around his neck. Police are investigating, and no arrests have been made.

Students were planning the music video weeks before the attack and wondered if it would be appropriate to continue their project, given the shock and stress that the school has been dealing with this week.

“This is more important now than ever,” said Sydney Fee, Bothell High School activities coordinator, who encouraged students to shoot the video with themes of strength, resilience, and overcoming adversity.

“To have these kids come out and support Bothell and then to dedicate it to Cal has just been awesome,” Fee said.

The students plan to screen the final lip dub video during a senior assembly in June.
