Have you ever flipped out over somebodies bumper sticker or t-shirt because it offended you so bad?

However, I was following a punk outside a mall once and right in front of me started slapping bumper stickers on all the cars in the row. When he put it on mine, I calmly ripped ip off before it set, and stuck it in his hair. He squealed a bit but probably didn't get it off without scissors or a set of clippers.
