Appearances can be deceiving

Today I thought about carrying around a flask or a bottle in a paper bag, but fill them with fresca (or any other beverage of my choice). People would see, assume, likely judge, but then I would have a scapegoat. When I say ridiculous/bizarre things, act like a goof, do something stupid or put my foot in my mouth, they'll all just cluck their tongues and go, "oh it's understandable... she's drunk". I could get away with absolutely anything!.... until the intervention, of course.
