a carrot in god's potato field

a) a social misfit, but someone who still somehow functions within their society.

b ) a person who doesn't follow professionally in the footsteps of either parent

dude 1) i can't understand why my parents don't appreciate me more. i want to a history teacher; my mom is a chemist, and dad is an engineer.

dude 2) did you lol ever consider that you might be a carrot in god's potato field, and that your parents wanted you to professionally follow in their footsteps. (starts laughing)
