A Holland woman got a rather nasty surprise in the US mail last week. Donna, whose last name has been withheld at her request, opened her mailbox to find a package containing a Ziplock bag filled with feces.

Donna tells WZZM the package contained a note that read, "You've been pooped on want to know by whom? Turn over."

The woman's son put on gloves in order to pull out the card and read the back. It stated, "You'll never find out who did this."

Donna tells the TV station she has no idea who would do such a thing and says she's had no complaints about her dog.

WZZM did a reverse lookup on the PO box where the package originated and linked it back to a website called poopsenders.com. The website claims it's not illegal to send poop through the mail for entertainment purposes.

Are you S---ing me??
