[preparing to try their flying machine]
Artemus Gordon: Hold on. Avanti!
[the bicycle speeds forward]
Artemus Gordon: Avanti! Avanti!
Capt. James West: Why isn't this thing avanti-ing?
Artemus Gordon: We're not getting enough lift! We need more speed!
[He turns toward a cliff]
Capt. James West: Artie, that's a cliff!
Artemus Gordon: Yes, I know!
Capt. James West: That means the ground is gonna end!
Artemus Gordon: Yes, I know!
Capt. James West: Gordon... Gordon... GORDON!
[the machine goes off the edge of the cliff... and sails into the air]
Artemus Gordon: It works! It works!
Capt. James West: If you had to get one right, Artie, I'm sure glad it was this one.
