What makes the main four Seinfeld cast's characters such a dynamic group is not necessarily their respect for one another, but their tolerance of each other’s shortcomings. However, one person whom Jerry Seinfeld’s onscreen alter ego could never bring himself to tolerate is his sworn enemy: Newman, played by Wayne Knight.

The question is, where did this feud start and what might we count as its peak moments of conflict? Let’s take a quick look at some of the best Seinfeld episodes and trace the history of Jerry and Newman’s clashes, quarrels and yada, yada, yada.
