Mail letters for free?

Depends on where you are mailing to and from. If you drop it off at your local post office they will deliver it to you with postage due!

I live in Canada and I do not have a mail box, but a central common box down the street, does that change anything?

I dunno. I'd doubt it would change much. I don't know if the Canadian Postal service will send mail "postage due".

Here they will deliver it because it is a local delivery and then they want the recipient to pay for it instead of mailing it back to the supposed originator.

You will be charged postage due in Canada. Also, mail fraud is a federal offense.

Don't think I'll be trying that.

I saw a comedian make a joke of it on the comedy channel that's how the idea came about. Intrepid, I looked up mail fraud and it's pursuant to consumer protection laws such as fraudulent solicitation i.e. defrauding people with gasoline voucher incentive programs.

Where do the mail fraud laws apply to postage?

Protection Against Fraud
Most marketers are honest business people, but you must protect yourself and your loved ones from fraud. The following are some tips on spotting fraudulent activity.
Recognizing a scam
Here are some classic signs of a criminal fraudster:

It sounds too good to be true
 You've won a big prize in a contest that you don't recall entering.
 You're offered a once-in-a-lifetime investment that offers a huge return.
 You're told that you can buy into a lottery ticket pool that cannot lose.

Taking action to circumvent legislated postal tarrifs is contrary to law and constitutes a form of postal fraud.

Now, if you wanna have some postal fun, without irritating the post office or the Feds, wrap a typical 3-pound building brick in brown paper, observing postal recommendations for wrapping parcels for mail, then affix to the package one of those prepaid postage return address lables from some junkmail solicitation and mail it off to the original sender of the junkmail. Your maibox will see no more from that advertiser, and you'll get a bit of a chuckle.

Would it be fraudulent to send doggy do?

This thread seems perfectly normal to me :-)

Were both in deep do-do then!

You may be right

I believe blood, urine, feces etc. samples are sent via mail and there are no issues if packed correctly. Do you think we could send a cadaver and see what happens?

if you write hedge in a box where the stamp goes write it in black ink then draw crisscrosses through the empty space above and below hedge in blue ink the system used to check postage will believe you stamped it.
NOTE-YOU MUST PUT A BLACK BOX THE SIZE OF A STAMP WHERE A STAMP GOES WITH ABOVE DRAWING IN IT.
