[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] George Archibald:
It's gin! It's gin! You've tricked me! Anthony Judson Lawrence:
That's right! [Takes the glass] Anthony Judson Lawrence:
Your Honor, I submit this as Exhibit D!
