The "Dinner Party" episode is after the "The Dog". In the "Dinner Party" episode, Jerry brags that he hasn't thrown up since June 29th, 1980. The black and white cookie ended this streak.

When JD arrives, he asks Keith what's the big emergency and Keith asks if he wants the patient to be prescribed unfractionated or low molecular weight heparin.

The choice between unfractionated and LMWH is an important clinical decision and should not be dismissed as "the exact same thing".
