Spiderman on a Train...Hanging Upside Down?

Okay, so I grew up in New York, and actually lived in "The City" for a year. Needless to say, I had plenty of experience riding the subway to and from work, or just getting from, say, uptown to downtown. And one thing is for certain: you never quite know for sure what you're going to see. Everything from panhandlers to subway musicians, and who knows what else. So imagine hopping on the train...and seeing THIS guy! Just another day on the train!
