DANVERS, Mass. (AP) - Who knew "Meep!" was a four-letter word?

The utterance favored by bungling lab assistant Beaker of "The Muppet Show" has been banned at Danvers High School in Massachusetts after students said it to repeatedly interrupt school.

Principal Thomas Murray says the word was part of a disruption planned using Facebook.

The Salem News reports that parents recently got an automated call about "Meep!" from Murray. He warned them that students who said or displayed the word at school could be suspended.

Murray says the warning was needed because students didn't heed his "reasonable request" to stop the meeping.

Danvers High sophomore Melanie Crane says it doesn't mean anything in particular.
