This is probably the most successful book to go through THREE different titles over the course of the run, but Keith Giffen and J.M. DeMatteis' Justice League always WAS a little different than others.
In any event, the idea of turning DC's foremost superhero team into, essentially, a superhero sitcom, was a brilliant move (and like many brilliant moves, one made of desperation, as Giffen was turned down the use of the characters he WANTED, so had to find out how to handle the ones he was GIVEN).
The result was sixty issues of hilarious dialogue, slapstick, schtick and schemes.
