It seems like it was planned

People are pricks man

The obvious solution is to take the package out, unwrap it, and squash it poop side down inside her mailbox.

Should have tracked her to her house. The old bag-on-fire-on-the-front-step-filled-with-poop trick.

I know a lot of mail is crap these days, but mail that actually is crap? That's a new one.

Call the police. File charges. Tampering with a mailbox is a federal offense.

Need to get your ass off of FML and clean out the shitbox.

When I see stories like this, I begin to think humanity peaked in the past and we are devolving into extinction. Are we not men? We are Devo.

And why did you just stand/sit there watching and not do anything?

It's time to return the favor, OP.
