SHEBOYGAN, Wis. (AP) -- School officials who had enough of inappropriate dancing' at Sheboygan North's homecoming halted the dance and warned students it would be canceled if they didn't clean it up.

A group of students began chanting obscenities at Principal Jason Bull when he took the stage at Saturday's dance. Bull told students that if they didn't practice better dance etiquette and be more respectful, the lights would stay on, the chicken dance song would repeatedly be played the rest of the night or the dance could end.

The Sheboygan Press (http://tinyurl.com/8th84le ) says there's an ongoing effort to clean up the dance floor at Sheboygan North. The dance capped a week of activities and celebrations marking the 75th anniversary of the school.

The dance resumed as planned following the warning.
