Chris Ganz, left, and Ben Lins hang upside down Thursday in a parking garage on the campus of Purdue University in West Lafayette, Ind. The two men along with fellow freshmen Ryan Herberger and Chandler Welsh began what they call "Batmanning" shortly after arriving on campus. Sophomore Robert Hansen, background, thought the stunt was impressive. A video of the foursome "Batmanning" on campus has since gone viral. All four men are engineering majors.
