What time of day is it? I ask because in the cool of night the ambient air is heavier, so the drag will be that much more (I own a turbo charged car, so I know a little something about air mass and temperature). However, because you're eating a Double Double from In-N'-Out-- animal style--, you're state of mind will be relaxed and happy. Because your mood is lighter, this will no doubt effect your actual weight (including the weight of the Double Double, of course). I can't back that up with any math, but I know it has something to do with Stevie Wonder and talking to plants. And don't worry about who's on third. Chances are you'll either strike out or be run down way before you get there.
