You bet. Those claiming not to are on a smear campaign.
BTW, Captain Midnight - legal or not, your idea sure is feral.
To get around the DNA issue, you could maybe pay some homeless guy to poop in a bag for you…
Just be sure to ask the homeless man’s name first. Otherwise, if the homeless name’s name is Sherlock, you will have no luck and out of cash. That’s because Sherlock is perpetually constipated.
Whut? You’ve never heard of No Shit Sherlock?
I note that Captain Midnight hasn’t made comment at all since posting the topic. Guess he doesn’t give a shit.
No, wait…!..
Didn’t they actually do this for the movie Pink Flamingos?
Does anyone else remember a company whose sole business was mailing dog poop to people? They had a website with a page telling all about their business but they seem to be no longer in business, which makes me think mailing poop is probably not legal…at least not if you’re doing it for gag/harassment purposes.
I know you can order chicken poop from gardening sites, though.
These guys owned a doggie doo cleanup service IIRC, got paid to pick up poop, then got paid again to mail it to the mark of your choice.
But to your original question, I’d bet the answer is likely no. I’d love to listen in on that phone call to the post office. 
Ask and ye shall receive: www.mailpoop.com
Quoted from their legal page:
Sure BigBertha; if the dog was the sender, its poo was human and Divine was the mailbox…
Thank you! I was telling someone about this and they told me I made it up! 
I bow to your google fu.
As soon as I started reading this thread I thought about the “gag” company. Guess you guys beat me to it on finding them.
This might be a legal barrier, but it’s certainly not a practical one. You can just make up a return address.
Is it illegal to provide a fake return address (assuming you’re not trying to get free delivery by using the return address as the destination)?
After a bit of perusing the US Code, I came across this:
Find that at 18 USC 1461.
I would say that excrement would absolutely qualify as being “filthy.” You could be put in prison for up to five years on the first offense, and ten years on subsequent offenses.
NO, special effects. It was actually chocolate pudding.
Here in Canada it is illegal. You know those stool test kits that test for occult (hidden) blood. You spread small samples on a card and it used to be legal to mail it to your doctor, but now you must hand deliver it. So even though it is totally harmless and not meant as an assault, it is still illegal.
In Pink Flamingos? Did you see it? That was the real deal.
I like that there’s an entire paragraph in there exempting the mailing of live scorpions.
Legal or not, it’s a crappy thing to do. :rolleyes:
Criminal considerations aside, it occurs to me that mailing poop to someone might be considered civil battery, subjecting the sender to a lawsuit for damages.
Dont mail poop, the secretary will look in the box and toss in half a second. Send them glitter wrapped up in a piece of paper and it will be all over their office, and them, for weeks. Theres also a company that mails glitter for you.
