A Star Is Bored (1956)

[Daffy is dressed as Bugs Bunny]

Daffy Duck : Oh, boy! I could be sent to prison for the scenes I'm going to steal!
[last lines]

Daffy Duck : I wonder where all the hunters are today?

[about a dozen hunters shoot at Daffy]

Daffy Duck : I demand to know who wrote this script!

Bugs Bunny : I'd like to tell him, but... Hehehehe... modesty forbids.
Daffy Duck : What a job for a duck with my talents, pushing a broom while others with absolutely nothing on the ball get all the breaks.

Bugs Bunny : [inside dressing room] Oh, it's so nice of you, Lolly...

Daffy Duck : Eesh! Listen to that ham putting it on.

Bugs Bunny : Well, I'm willing to do anything my public demands.

Daffy Duck : [mockingly] "Anything my public demands. Anything my public demands." That does it! If a long-eared rabbit can be a star, so can a duck!
[repeated line]

Daffy Duck : Make up!
Producer : [on phone] Yeah. Yeah, I know we need a double on the Bugs Bunny picture, but where can I get anyone stupid enough to take the job?

Daffy Duck : Okay, boss, hang up. A star is born, and that star is me!

Producer : I'll call you right back. I... I think I got a pigeon.

Daffy Duck : Pigeon? I'm not a pigeon. I'm a duck. D-U-K, duck. Loaded with talent. I do card tricks and impersonations. I work at weddings, bar mitzvahs... Have tux, will travel.
