Four people could face jail time for cheering too loudly at a Mississippi high school graduation, NBC News reported. Authorities have charged them with disturbing the peace, punishable by up to six months in jail and a $500 fine, for disrupting commencement exercises at Senatobia High School on May 21. One of them cheered, "You did it, baby!" when his sister's name was called and was promptly whisked outside, his mother told NBC affiliate WMC in Memphis. The chief of campus police at Northwest Mississippi Community College, where the ceremony was held, told NBC News that his officers were instructed to take disruptive people out of the coliseum. The superintendent, Jay Foster, who pressed the charges, told WMC that outbursts at past graduations have lead to some graduates being unable to hear their names called. The four family members are scheduled to appear in court on June 9.
