I've coined a new phrase: Hey it's your rodeo; I'm just the clown. It is for annoying superiors.
How did you come up with that?
I was inspired by my friends gf. I don't have any control at work.
That's an amusing phrase! However, if you think it would annoy your superiors, it's a good idea to use the phrase elsewhere if you want to remain in their good graces.
My superiors should be more objective and also I think they don't like to be challenged.
Your assessment of them can be right, but this phrase is not the way to bring it up to them. Talk to them in a more professional manner and your concerns may be heard.
