Is he a cartoon hall of famer? Is he up there with Bugs, Mickey, Tom and Jerry, the Flintstones and the rest? Or is he a generational fad like the Smurfs?
Consensus I have gotten from informal polling has suggested that he is close but needs to go through the "waiting period". In sports an athlete needs to be retired for 5 years before consideration of hall of fame status. So Mr SquarePants is still in production of new episodes so even though he has lasted 10 years he needs to stop making new episodes and then wait 5 years before he makes it. \
I say he's in. The current generation of kids loves him and we can safely assume the enxt generation will as well. Parents of this generation, the Gen Xer's love him, so that gives him three generations of fans. He'll be on the air for the next 30 years without fail. Skip the nonsense and call a duck a duck! Fire up that clarinet Squidward and play that marching tune SpongeBob and the gang should go straight to the Hall of Fame.
