Frank Grimes is one of the most sane persons in the tv show The Simpsons. When you look at Homer from his point of view you kind of have to agree with him.

That last scene where they are all at Frank Grimes funeral and Homer is half-asleep saying "change the channel Marge!" during Reverend Lovejoy speech and everybody is laughing while Frank Grimes casket is slowly put in the ground was pure gold.
