Or sitting in shit. On a side note, I actually got on the subway one day (at rush hour on a weekday!) and to my horror, saw a seat covered with shit. Not even dog shit, human shit! I should point out, this was not just like someone had an "accident" or anal hygiene violation, someone actually dropped trow and took a shit. Needless to say, the smell was horrendous. A tip: If you ever find yourself in Philadelphia and use the Market Frankford Line, and get on car 1137, I would stand! lol
