Minimum contacts? What the hell are they, some new Johnson & Johnson disposable lenses?
Kidding. Although, I am curious if your professors had a stick up their ass when it came to the phrase "minimum contacts." Some professors favor the more verbose "sufficient minimum contacts," while others prefer "sufficient contacts," arguing that use of the word "minimum" implies some sort of quantity that will suffice, when it is really a qualitative test.
God... I need a life. Finals are over, why do I care?
