It's funny, because if you do drink soda in a paper bag a cop will definitely stop you and question you. That's why I pour my beer in a rootbeer bottle. (Not rlly since I don't drink, but if I did I would)
My sophomore year in college I somehow was assigned to a substance free dorm. My first night there I put a 40 oz bottle of tea in a paper bag and offered it to my RA....I think she is still having palpitations.
