Katherine Heigl probably didn't realize that when she was exiting the super market over the weekend that she would be swept up in a one-man, pro-America rally!  Check out what happens as this zealot waves the American flag in the paps' faces (albeit upside down), knocks someone's camera to the ground and gets in between Katherine and her groceries! Luckily Katherine was a good sport about the whole thing and laughed it off; unlucky for that dude that they got his license plate number!
