Chicago.. duh..

You're walking, about to cross the street to meet your husband and your kids at a parent-teacher conference. Before you cross, a man bumps into you, wearing a mask and fedora. He trips and catches you before you can fall. He smiles and looks away as he stands next to you at the crosswalk Sorry.. His voice is quite unique and for some reason he's wearing a varsity jacket, mask, and hat in 94 degrees weather while walking alone in downtown Chicago.. What's your name?
