Donald Duck: [Reading sign] "Experimental Laboratory, Camouflage Corps. Keep out"
[Goes in]
Donald Duck: It didn't say "positively."

Sgt. Pete: [catching Donald painting a cannon in rainbow colors] What are you doing here?
Donald Duck: I'm a camouflage painter.
Sgt. Pete: Camouflage?
[Sees the rainbow colors Donald painted on the cannon]
Sgt. Pete: Why, you fool! You got to paint it so you can't see it!
Donald Duck: [subdued] Ohhh... I didn't know.
Sgt. Pete: Get some new paint, and make that gun hard to see!
Donald Duck: Yes, sir. Oh, why don't somebody tell me these things?

- Clarence Nash in The Vanishing Private

Sgt. Pete: Good morning, General. Did you see a little guy that you can't see?

- Billy Bletcher in The Vanishing Private

[last lines]
Sgt. Pete: [Pete is in a cell, trapped in a straitjacket] I ain't crazy. You know I ain't crazy! Go tell the general that I ain't crazy.
Donald Duck: Do you think *I'm* crazy?

[Pete notices the cannon supposedly missing, when Donald simply painted it invisible]
Sgt. Pete: [shocked] The cannon! It's gone! A fifth columnist! He stole our cannon!

- Billy Bletcher in The Vanishing Private

[the General catches Sgt. Pete throwing grenades everywhere, trying to blow up the invisible Donald]
General: Just a minute, man!
Sgt. Pete: He can't make a fool outta me!
General: Do you mean the little man you can't see?
Sgt. Pete: Yeah, yeah! He's around here skipping rope. I'll get him!
