no one in his/her/their right mind would (do something)

No one who is sane would consider doing something; someone would have to be crazy to do something. (In this case, "their" is used as a singular, gender-neutral pronoun.) All I'm saying is that no one in their right mind would ask the boss for a raise with the economy the way it is right now. Everyone knows Jake is a mess—no one in her right mind would date him.

COMMON If you say nobody in their right mind or no one in their right mind would do a particular thing, you mean that it is a stupid or crazy thing to do.
