When nature calls

Shitting on Pennywise is not a bad thing. Unless it was the band. In which case you'd better apologize.

To your defenses, when you gotta go, you gotta go. Nice of you to do it on a sewer drain, it'll be washed away during the next rain.

Storm drains generally are not septic sewers. They generally go straight to waterways without the rigorous water treatment you'd get in a septic sewer. You'd have been better off to shit on the grass and pick it up with a bag like we do with dogs. Of course if it was the runs, then you're screwed no matter what.

Actually it depends where you live and how old the sewers are. Most of them actually are what is called 'combined' system, where everything (wastewater + rain) goes to the same place. The 'separate' systems are in areas with new properties, new roads etc. or in small areas where flooding problems have lead the Council/State to remove the existing system and put a new one, which is super expensive.
But yeah sure taking a dumpon a gully and leaving it there is not ideal.

I mean, that's where it ends up. you just took out the middle man.

Well, at least you didn't leave it right in the street.
