On the bright side there's no streaks now!

Quite the strong stream to hit your windshield. He must've really had to go!

quite the arch indeed

you should have ran him over

I beat you to #1 ;)

Yeah! Then taken his wallet!

Yeah! Commit homicide! That'll show that rude fucker!

There are two types of people...

... go on?

or honk your horn and scare the shit out of him! literally

I think you missed the 'waiting a a red light' part.

He was trying to wash your car.

Free car wash!

My thoughts exactly!

I'm sorry, do you always use urine to wash your car?

#9: Yes.

#9: is there a problem with using more natural ingredients to wash one's car?

#13 - Ammonia does a rather beautiful job, if I may say so myself.

Give him a little nudge with your bumper, he should stop pissing then :)

Yes, because I'm sure OP is still sitting at the red light, his car getting pissed upon.

It's raining!!! The rain smells like asparagus...

Should have pressed the gas. Just kidding that would be much worse. Then you'd have blood on your car along with piss...

You could just tell the police the car belongs to Andres Serrano.

Forget it. He's drunk...

So, by that logic, if he were to get in a car whilst drunk, and kill a few people, we should just "forget it," because he's drunk?

I think a certain degree of how serious his actions were play into this. By your logic you would react similarily to a person running over people whilst drunk and a person making inappropriate jokes whilst drunk. Something small is pretty much forgivable in my book.

Should have pretended to be a mobile urinal and nudge him in the knees a little... Oops, was kinda thinking out loud for a sec...

Think quieter.

Now that's bad luck

Not necessarily. What if he was cute and OP wanted to see him with his pants down?
