What's the scariest/funniest/randomest/craziest thing that's happened to you on public transportation?

Have you ever had any interesting, or memorable, encounters while riding public transportation?

Two years ago in Chicago after a concert at the United Center, the bus was so full, we were packed like sardines. I had my son with me and should have taken a cab but the wait for cabs was so long I didn't want to hang around as the crowd thinned and the option to hop on a bus no longer being there.

So, on this crowded bus we went. We were standing in the isle and this lady by us was super drunk and just looking for a fight. She started to rant that someone should give me and my son their seat because he was a kid (age 11). I didn't want anyone to give up a seat and tried to tell her we were fine but she just wouldn't shut up and was berating all the men around us for not giving us a seat.

My tit popped out on the bus, I've seen a fight on the train where this one dude kicked the assess of the two dudes that tried to jump him, some bad singing, a few Jesus freaks, this one crackhead who got on the bus was raving like a lunatic, he was funny as hell though, a couple of mire scuffles, etc, etc. It's nothing new on NYC public transportation.

Don't have any. It's been so long since I've taken public transportation. Even when I did, nothing out of the ordinary happened.
