I used to ride the trains in Philadelphia all the time. In fact, I moved to places specifically so I could walk to the stations. Then when it was off season for inline skating and I needed an aerobic buzz, I'd get off the train a couple stops early and walk the extra mile .
There were times when it was less than perfect. If the system had a problem and I had to stand, if it was too crowded, that sort of thing. This seems to be one of those kind of trips.
Fred mistakenly gets on a bus full of war veterans, but upon discovering it is going his way, decides to stay on for the ride...
He sits down next to a guy that jerks his head to the left every few seconds, over and over. This really starts to get on Fred's nerves so he asks him, "What the hell is wrong with you?"
The reply is, "l got this in the war."
Fred finds this pretty annoying so he switches seats. The next guy he sits by has uncontrollable spastic twitches in his right leg, causing him to kick the seat in front of him, and even kicks Fred a few times. So, Fred asks him, "What the hell is wrong with you?"
Again the answer is, "l got this in the war."
Fred moves. The next guy poor Fred sits by begins erratically flailing his left hand. Fred says, "Let me guess, you got that in the war."
"No, l got it out of my nose. Now I can't get it off of my hand."
