Seinfeld, indifference and irony

My understanding of why i like Seinfeld took a big step forward. All four of the characters have a hefty level of indifference towards most things, even Elaine (what a woman). Because of this the show overwhelms with an excess of irony. Their indifference implements many of the key ironic moments, they appear to constantly test of the boundaries of convention within everyday life.
Tommy. 

This feels very much like a situation i could have instigated.
