Homer: I want to tell you about the most wonderful place in the world: Doggie Heaven. In Doggie Heaven, there are mountains of bones, and you can't turn around without sniffing another dog's butt! And all the best dogs are there, Old Yeller, and about eight Lassies.
Bart: Is there a Doggie Hell?
Homer: Well of course, there couldn't be a heaven if there weren't a hell.
Bart: Who's in there?
Homer: Oh, uh Hitler's dog and that dog Nixon had, what's his name, um, Chester
Lisa: Checkers.
Homer: Yeah! One of the Lassies is in there, too. The mean one! The one who mauled Timmy!
