Elmer Fudd: (pulls rifle trigger) Well, what do you know? No more buwwets.
Bugs: No more buwwets?
Bugs: (to Daffy) Hey, Laughing Boy, no more buwwets!
Daffy: No more buwwets? Here, let me see that thing.
(Daffy looks into shaft)
(the gun fires in Daffy's face)
Elmer Fudd: Well, what do you know? One buwwet left!
