I know of an exchange between a ref and a coach that went something like this:
Coach "Ref, what's the problem? You can't see that what she did was clearly a foul?"
Ref "Sir, if you don't stop saying this stuff, I'm going to red card you annd throw you out."
Coach "Will you throw me out for what I think?"
Ref "No"
Coach "Then I think that you are a (expletive) idiot."
