I visited my favorite shop, and there is a "tough guy" college student working there. We were talking our usual smack to each other, and we were talking about fighting or something. The tough guy gives me a defiant look and challenges me to take him on right in the shop. I figure I'd screw with him, so I start to move my arm but then I surprise him a little head fake. He flinches and put his hand up to protect himself from my nothing move. I start laugh and tell him "Psych!". Ever play the flinching game?
