MICHELE NORRIS, host: To New York City now and reporter Soterios Johnson, who tells us that in      one neighborhood, the sound of spring is unmistakable.</s>SOTERIOS JOHNSON reporting: It's called primal scream.  And like the return of the swallows to      Capistrano each spring, it happens like clockwork; in this case, at      midnight the Sunday night of finals week at Columbia University in      Morningside Heights.</s>JOHNSON: This time of year, students are full of hope because the end is      near and are full of stress because, well, the end is near.</s>Mr. DORON KENTER (Senior, Columbia University): Screaming is always      good, especially during finals, like a bonding activity.</s>JOHNSON: Columbia senior Doron Kenter.</s>JOHNSON: It's not really clear when the tradition started, but Columbia      students have been screaming for decades.  Robert von Gutfeld has been a      Morningside Heights resident for a half-century.</s>Mr. ROBERT VON GUTFELD (Morningside Heights Residents): No, I don't mind      the screaming.  Occasionally, it's awakened me and I wonder if they're      being raped or skewered.  All right?  But then it's Columbia.</s>JOHNSON: Within five minutes, it's all over, the neighborhood's usual      tranquility restored, at least until finals week in December.  For NPR      News, I'm Soterios Johnson in New York.</s>ROBERT SIEGEL (Host): This is NPR, National Public Radio.
