- Hubie: Bert, an average mouse eats 12 pounds of cheese in a lifetime. I figure tonight we've lived 2000 years.
- Dog: [the dog is at an adding machine] Let's see now. Mice don't like cheese...
- [types on machine, pulls lever]
- Dog: ...and mice want cat to eat them.
- [types on machine, pulls lever again]
- Dog: Now then, cat don't wanna eat mice...
- [types on machine, pulls lever again]
- Dog: ...but cat wants dog to massacre him.
- [types on machine, pulls lever again, and looks at results]
- Dog: It just don't add up!
- [Dog then hears a dog pound driving by and runs to it, and runs away from Claude, Hubie and Bertie]
- Dog: Hey, take baby!
- Claude Cat: [while running up to runaway Dog] You forgot to massacre me!
- [Hubie and Bertie run up to Claude Cat and the Dog, as the closing credits start]
- Dog: Wait a minute, wait a minute. Now, uh, you're a cat, right?
- Claude Cat: Right.
- Dog: And, uh, cats eat mice, right?
- Claude Cat: No!
- Dog: You - he-he - you're mice, right?
- Hubie: Right.
- Dog: And mice, they eat cheese, right?
- Hubie, Bertie: Cheese? Ahh! Don't mention that word!
