IF a person were to, for the sake of art or science, sit down and watch every episode of "The Simpsons" ever made, it would take him more than a week of no-sleep, back-to-back viewing in 350 half-hour increments.
In that marathon the viewer would learn that life on a street called Evergreen Terrace never really changes, that Bart, Lisa and Maggie, along with their creator, Matt Groening, will not grow up, and that the Simpsons, once viewed as the shock troops of cultural mortification, are a shining exemplar of family stability in the come and go world of television.
