Do you like windows? You'd better hope so. After five straight stops with all pickups and no exits, your face and the window are about to get pretty well acquainted.

Sure, some public transportation vehicles are incredibly clean. Others have more germs than a gas station bathroom. Probably because some people mistook it for an actual bathroom.

Some performers in a subway can actually be pretty entertaining. For others, the reason they're not famous is pretty obvious.  But it doesn't matter, because if you're stuck in a subway car with one of them, you're literally a captive audience.

"Oh you have a book? Cool, instead of taking that as a sign you want to be left alone, I'll use this as an opportunity to try out my lame pick-up lines!  I've got 300 of them, let me know if any work!"

"Hey, since we're on the subway together, wanna do some hard-core making out?"

"Sure! The subway is gross and full of germs, which makes it one of the sexiest places around!"

No matter where you stand, you're bound to get an armpit directly in the face. And at the present time, there's no law requiring all subway passengers to wear deodorant. If you're not skilled at holding your breath, you're screwed.

Train and bus routes can be tough to navigate even if you've lived in a city your whole life. But if you're just visiting, it's even worse. Hope you enjoy paying four bucks to accidentally go uptown, transfer to another train, and then wind up in Brooklyn at four in the morning. Because that's what's going to happen.

This is either a very insensitive guy, or a genie in the middle of granting a wish. We're hoping it's a genie. That way we can wish that no person ever sits like this ever again.

He must be very tired, and needed a one-way ticket to dreamland. Unfortunately everyone sitting near him got a one-way ticket to nightmare-land.

Some people on public transportation have a little more decency than to sleep while taking up a few extra seats. Instead, they'll fall asleep directly on top of you. Did you know that your shoulder makes for a pretty effective pillow? Well, you do now!

Sure, this skill might come in handy if the train is crowded and there are no seats. But someone should let him know about all those empty seats to his right. There's no way sitting like this is actually comfortable.

When you ride public transportation, you have to deal with people doing very strange things. Like this lady, who thinks the car is just an extension of her kitchen. It just goes to show that when you ride the subway, sooner or later you'll be driven to tears.

If you use public transportation, you might be sharing a ride with these guys, and nobody wants that. Creepy dolls are no fun to share a train with. Partially because they're probably murderers, but mostly because they're hogging some really good seats.
