The BRM isn't looked at by the company who sent it. It goes to a lockbox firm somewhere, who opens it and processes the contents. It it doesn't meet their requirements for processing the credit card app or whatever it is, it goes in the trash.
Some other things not to try:
Putting foreign objects in the reply envelope and sending them. Best case scenario, nothing happens, and it goes into the trash can upon receipt at the lockbox.
Mid case scenario: the packet of liquid you put in there breaks open, leaks out into the tray, and damages other people's mail.
Worst case scenario: the envelope of foot powder you tossed in as a joke or prank breaks open in the machine, shuts down the postal facility, and you go to jail for delaying the mail, and get a nice fine to boot.
Writing nasty messages all over the outside of the return envelope: The Postal Inspectors come and pay you a visit for making terroristic threats and using the mail to make threats.
In short, toss it in the trash and be done with it.
