An intriguing aspect of Seinfeld is Jerry's unique style of comedy.  A lot of the jokes are just common observations turned in to a clever or witty comment.  The show pokes fun at the obvious.  It uses retinue and every day stuff.  An example of this is Jerry's idea on same side couples at restaurants.  In a episode he remarks to call couples like that disgusting and just asking for attention.  An account that one might see at dinner and Jerry pokes fun at it, and turns it into witty humor.
