I think this song pretty much sums up all of the show's great moments plus it's a great moment in itself.
Ullman shorts,
Christmas show,
Marge's fling,
Homer's bro,
Bart in well,
Flanders fails,
Whacking snakes,
Monorail,
Mr Plow,
Homer space,
Sideshow Bob steps on rakes,
Lisa's future,
Selma's hubby,
Marge not proud,
Homer chubby,
Homer worries Bart is gay,
Poochie, U2, NRA,
Hippies, Vegas and Japan,
Octuplets,
And Bart's boy band,
Marge murmers,
Maude croaks,
Lisa Buddihst,
Homer tokes,
Maggie blows Burns away,
What else do I have to say?
They'll never stop The Simpsons,
Have no fears, we've got stories for years,
Like - Marge becomes a robot,
Maybe Moe gets a cell-phone,
Has Bart ever owned a bear,
Or, how 'bout a crazy wedding?
and something happens a do-do-do-do-doooo,
Sorry for the clip-show,
Have no fears, we've got stories for years.
