Best. Simpsons. Ever.

I've just watched Bart vs. Australia (Season 6) and I've decided this is the perfect Simpsons, which is odd since the peripheral characters are hardly in it. Lee would you agree? I know it's one of your favourites. What are your favourite quotes? The next episode on my DVD (Homer vs. Patty and Selma) contains the immortal line from Patty (or Selma?) to Marge: "When are you gonna wake up and smell your husband?" I also like Homer answering the phone whilst wearing only a towel: "YOU'LL HAVE TO SPEAK UP - I'M WEARING A TOWEL."
