The Young Philadelphians1959

[At Chet Gwynn's murder trial, Anthony Lawrence sets up a demonstration to test butler George Archibald's ability to name a type of liquor by smelling it]

George Archibald:
[Sniffing a glass] It is Royal Tartan Scotch. Unmistakable. Rich heavy bouquet with a definite aroma of peat smoke.

Anthony Judson Lawrence:
[Hands him another glass] Now, the third glass.

George Archibald:
This is water, sir. There is no smell, except perhaps for a faint touch of chlorine, which the city puts in its drinking water. I trust you weren't trying to trick me into identifying it as liquor.

Anthony Judson Lawrence:
It's water? Are you sure? I don't understand.

George Archibald:
You will note there is no label. I believe you gave me your water glass.

Anthony Judson Lawrence:
Well, I'm terribly sorry. I guess I made a mistake.

George Archibald:
Well, perhaps it's not in vain. Since my throat is a little dry, you'll pardon me. [He drinks the glass, coughs] It's gin! It's gin! You've tricked me!

Anthony Judson Lawrence:
That's right! [Takes the glass] Your Honor, I submit this as Exhibit D!
