We’re in the stickiest situation since Sticky the stick insect got stuck on a sticky bun.
And not a one liner, but this gets me everytime:
Blackadder:
I wonder whether, having been tortured by the most vicious sadist in the German army, I might have a week’s leave to recuperate.
Melchett:
Splendid idea! Your commanding officer would have to be stark raving mad to refuse you!
Blackadder:
Well, you are my commanding officer.
Melchett:
Well?
Blackadder:
Can I have a week’s leave to recuperate, sir?
Melchett:
[outraged] Certainly not!
Blackadder:
Thank you, sir.
Melchett:
BAAA!
