The president of Southern Adventist University, Gordon Bietz, dyed his hair purple on Feb. 10 for a good cause.
Bietz, whose normal hair color is white, had a deal with Southern students: If the students could raise more than $5,000 for a literacy project, he would let his hair be dyed a different color.
But there were more surprises than just a new hair color.
The university gathered to hear students running for a student association give their election speeches.
At the start of the program, it was announced that the students had raised enough money and that Bietz would go get his hair dyed during the speeches.
However, after the speeches were given, when it was time to show off Bietz' new hair color, it was announced that there had been some issues and that Bietz would meet the students in the cafeteria.
Before the crowd could leave, a flash mob made up of students and professors suddenly appeared. Dancing to David Crowder Band's "Oh Happiness," they celebrated the students' achievement.
Bietz then emerged from the mob with his new hair do.
