Manhattan real estate broker Sean Futterman said he snapped the picture about 6 p.m. Monday at the 96th street station on the Upper West Side. Advertisement Futterman said the train -- believed to be the No. 2, 3 or 5 train -- was pulling into the station when he and other witnesses spotted the three youngsters hanging on to the back. Futterman said he and other bystanders shouted at the kids to get off the train, but they only laughed and shouted profanities in response. He said there were no police officers present at the time. "Stupidity knows no bounds," MTA spokesman Kevin Ortiz said in response to the picture. Some observers pointed out a strange image under the train that appears to resemble a skull, but Futterman dismissed the image as a trick of the light. "Subway surfing," the practice of riding atop and outside of trains, began in the 1980s and has been blamed for more than a dozen deaths.
