What do you do when you get bashed by your manager for no good reason?

Luckily, I have a boss who is cool headed; but I hear stories, often funny, from some of my unfortunate friends who have hot headed managers who bash them for no reason with unreasonable expectations. Do any of you go through; or have gone through in the past; with similar mangers? How do/did you respond? Share some GIPHYs, yo! 😀
