Dry Clean Only

So I was on the train the other day...

...and I'm moving through the cars. When I looked into the window of the last train car, I noticed a hobo cleaning himself with a newspaper. Part of me was happy that he recognized the importance of hygiene, another part of me realized there was no water and the last part of me came to the conclusion that I didn't need to be in that car.

Unfortunately, he got picked up by the cops at the next station, as cleaning yourself is apparently, somehow a crime.
