when i worked as a body man ford a ford dealer, i found a empty whiskey bottle inside a van door (the guy was complaining about a "thumping sound" every time he opened or closed it. also found a factory tool jammed in a spot in the a pillar with a note attached to it saying "you lucky *******, you finally found it". then one of my buddy's had to pull a trains out of a then bran new tempo because it wouldn't move (it didn't even have 10kms on it). when he pulled the trans, someone at the factory wrote "F*&K YOU" on the torque converter.
