My fave from the old shrink was "You DO realize that's not a normal thought process?"

To which I replied "No spit! WTF do you think I'm doing here? Oh I know...I had nothing better to spend my money on than your retirement fund.....DUH!!!

She was not amused at all but then again neither was I. I was pretty ticked by that point. It was her tone of voice and inflection GRRRRR
