This unbelievable video was recorded at a recent high school graduation.
A disagreement over saved seats turned into an all-out brawl, involving multiple families.
The fight erupted across two rows of seats while the graduates walked down the aisles and up to the stage at the beginning of the commencement ceremony.
The school released a statement saying:
"It was unfortunate that a couple of adults in the audience exhibited the behavior they did prior to the ceremony beginning and thus has caused a distraction from the celebration of our students' accomplishments. The graduation ceremony was not affected by this incident due to the actions of Bellevue's security team who promptly removed the adults from the ceremony."
