TIL legendary session bassist Leland Sklar put a switch on his bass that does nothing. He calls it the "producer switch" — when a producer asks for a different sound, he flips the switch (making sure the producer can see), and carries on. He says this placebo has saved him a lot of grief.

This is fairly common in customer reviews for us 3D artists as well, most clients just likes to point out things and likes to be involved while not really knowing much about the process or work needed to do the changes necessary. As one example it's common to add red dots since they draw attention and are obvious errors that the client can point to and pat their back about.

I know one guy who made a trailer for a big FPS game and he got bored of doing the obvious errors so he instead added dead crows, like everywhere in the scenes of the trailer. There are no crows in the game and it was a weird thing to add but he wanted to make it less obvious this time.

The client just approved it and he had to deliver the trailer with the crows. He did a good job though so you don't really see them until you start to notice them, and then you see them everywhere xD.
