- No outside force can harm the Coyote—only his own ineptitude or the failure of the Acme products.
- The Coyote could stop anytime—if he were not a fanatic. (“A fanatic is one who redoubles his effort when he has forgotten his aim.” — George Santayana)

- Whenever possible, make gravity the Coyote’s greatest enemy.
- The Coyote is always more humiliated than harmed by his failures.
- The audience’s sympathy must remain with the Coyote.
