When choosing a seat on the crowded 7:47 express out of Framingham into Boston, pick one next to a woman or an Asian. Or better, an Asian woman. A woman is more likely to move over into the center spot than a man, giving you the aisle. I've actually asked women if they don't want that aisle seat, that it's okay, that I'd didn't mind sitting in the middle and they always declined. A woman, and an Asian, will more likely be smaller than a man, so there will be more room. Women and Asians won't sprawl all over the place like a man has a tendency to do, staking out his spot in the urban jungle.
Note to the two hogs I had the pleasure of sitting in between this morning on the commute in:
To the doof on my left. Yes, you're a doof. You need to lose a substantial amount of weight. And I'm not sure why you had to sit there with your legs spread, but dude, if you were getting off on me you're damn lucky I didn't have coffee yet.
To the John Cleese look-a-like on my right: Lose the hat. I know it was expensive, but there's no hope left for you. You look like a cuckhold, and your Indiana Jones hat ain't gonna save you.
