Some unexplained rattling in the blinds freaked out one of my middle school chorus classes. The windows and doors were closed, no one was near the blinds, and there wasn't a fan on at the time. After hearing the clattering, the teacher, Mr. B., started singing to the tune of Ray Parker, Jr.'s "Ghostbusters," "If there's something strange in your classroom, who you gonna call?"
Before Mr. B. could sing the answer, "Ghostbusters," however, a student called out, "The janitor!"
Not a bad response, by the standards of early teenage humor...
