Sorry for your plight fellow Rams brother but eventually the worm will turn and you will have your day. It is amazing that someone spent so much time and effort to do that. Thanks for the pics.
During the Bill Walsh/Joe Montana days when the 49ers were hot, and while I was in living in San Jose, CA, there was verbal abuse but nothing quite as elaborate as what you got.
Back in the late 70's I was hired for the shipping/receiving department of an electronics company. There were three guys who worked with me there. We were isolated from the rest of the building. No bosses ever came around. Since I was the new kid on the block, these other guys terrorized me on a daily basis. They had a fascination with super glue. The contents of my desk, the desk itself, the phone, and even my chair was super glued at times. Then there was them messing around with the food I brought in for lunch. You get the point.
The thing is that all three backed their cars into the parking spaces which meant the back of their cars were hidden by bushes. So I had bumper stickers made up which I can't describe here and still be a good mod
and put them on the bumpers of their vehicles. The point is that once I stopped complaining to the bosses and took action they backed off. Eventually one got fired, another got arrested at work and never came back, while the last one was killed in a car accident driving home drunk from an Oakland A's game.
