“What’s wrong with you, do you have brain damage?”
“Are you lazy or stupid?” (Both statements from former boss, and these statements were said to me when I was in the process of working full time and completing a master’s degree).

Also said to me, “if I was you, I’d be angry right now.” (I’m someone that shuts down unfortunately when someone is chewing me out, well especially, if that someone is my boss). (Now I did write down most of these nasty remarks and reported it to her supervisor).
