My older brother had his yearly review at work recently. And his boss told him that he might want to work on how he takes constructive criticism. My brother should have graciously accepted this criticism and pledged to work on it. But my brother finds it too hard to pass up an opportunity like that. So, the hilarious comedian that he is, my brother decided it would be funnier to respond with a joke. So he told his boss to "shove it."
Needless to say, that didn't go over very well. He had to backtrack pretty quickly and explain to his boss that he was merely making an ill-timed joke and he didn't really mean for him to shove anything. But his boss didn't find it as humorous as one would have hoped, so the yearly review was wrapped up quite nicely with a written warning.
I think my older brother learned a valuable lesson that day. And I learned a really good response if someone ever tells me I should work on accepting criticism.
