When young, I was the "channel changer."
Even worse was "Rabbit Ears." You walk close to the TV to adjust the antenna. Picture looks great while you are standing there. You have to repeat this cycle for 15 minutes every time you change the channel: adjust antenna, step back, watch, step forward, adjust antenna, step back...
Then once you have the picture perfect and go sit down, someone comes into the room. This person stands too close to the TV, looks and says "this picture is terrible" and before you can speak, messes with the Rabbit Ears. All that stress getting it perfect for nothing.
