"I tease him and act like a jackass while looking him slyly in the eye so he won't react.  So it seems that all is good because you know he won't react at the moment, but make no mistake: someday when you do the wrong thing he'll be a little bit more likely to slam you, and reprimandation  is no joke around here.  You can easily end up gone."
"So why do you do it?"
"I have no fucking idea.  We're allowed a little bit of that around here."
"Of being a jackass and teasing your superior?"
"No.. of having no fucking idea."
