Teachers don't like it when students talk during exams—but one teacher in New Mexico apparently really doesn't like it. Police say Benjamin Nagurski was arrested Friday after allegedly pulling a knife as kids chatted during a pop quiz in his math class at Bernalillo Middle School, and the police chief says the charges he faces are "very serious." Nagurski was booked on charges of aggravated assault with a deadly weapon and carrying a weapon onto school grounds, both felonies; he's currently out on bail, KOAT reports.
"One of the teachers there allegedly turned around, had a knife in his hand, and pointed it toward some students" about 4 feet away, the police chief says. Students told police that Nagurski was upset with one boy in particular, telling him, "Maybe next time I'll pull a machete on you," the AP reports. But Nagurski, 63, claims he was using the knife to remove staples from a bulletin board and just happened to have it in his hand when he turned around to scold the students, the chief says, adding, "That certainly wouldn't be the best method to remove staples." The school's principal called the cops, though it's not clear how he learned of the incident. (More weird crimes stories.)
