Nine high school students in Grand Rapids have been suspended for performing a version of the "Harlem Shake" during class.
The Union High School students were suspended for two days.
They filmed themselves dancing on Thursday and posted it online.
The "Harlem Shake" is an Internet dance craze.
A substitute teacher was with the class at the time of the incident at Union High. The teacher was sent home on Thursday.
More than two-dozen students also were recently suspended from Milford High School in Oakland County for recording a version of the "Harlem Shake."
